Just a quick update and a photo. I found out that I am 11th of 64 bikes entered this year in the point chase and 35th out of 172 total vehicles. That's pretty good for a first year bike and if I can make all the meets I fully intend finishing higher. 35th in points means I will run in the 35th position for the July meet. Which means by 8:30 A.M. which means no racing in the heat unless I make a second pass. Here is the bike going through the traps at 167. Scott  | ||

Scott: What a great thread--thanks for carrying us along with you! rt | ||

Scott, I must echo Road Thing. Here's to you. Your determination with the build AND the documentation of it is admirable  ...and a little goofy. | ||
| Isiahstites |
Thanks Road thing and Rasta dog! Ok, what the hell do I do that is goofy?? Maybe you are mistaking goofy for the passion for motorcycles that I have that most confuse with feffing crazy!! Scott | ||

Scott, What day are you leaving for Bonneville? Me and Tim are going this year and if you want we could caravan up. Don't know what time you would be going though, Chuck. | ||
| Isiahstites |
I am thinking of leaving the 14th or 15th of Sept. There is a race at El Mirage on the 14th and I am trying to decide whether or not to make one pass to stay in the points race. When did you guys plan on leaving and where do you live? I may go up through Reno and stay the night, everything is kinda up in the air. Scott | ||

Scott, Just a little barb at you 100% in jest!  What I really mean is that I'm thankful for the fact that you take the time to document and share this with everyone. Sincerely, Mark | ||

Scott, I will get back to you on the date we will leave, last year we drove all the way in a day. We live in Long Beach just up the road from you, So your racing in the same class as Tim is, I think??? Should be a great time, We missed last year!!!! If it don't work out I hope to see you out there, Chuck Horton. | ||
| Isiahstites |
Let me know what your plan is Chuck and we will try and work something out. If not we can meet up on the salt. Scott | ||
| Charlies_s1 |
Scott sounds like we are going to different events, We are going to the Bub event on the 2nd to the 7th. Oh well have a great time and hope you reach all your goals, Haul ass my friend, Chuck. | ||

Scott the parts I have for air shifting is the air ram , engine kill switch, I can give you them if you want , I also have a air bottel but not in good shape. if you want this stuff let me know. Daryl | ||
| Isiahstites |
Charles - Good luck! Maybe next year I will go to the BUB event. Hutch - I do want the shifter parts. I am sure I can wip the bottle back into shape. Thank you I really appreciate you helping me out. Scott Scott Stites 4835 Gardenia St Oceanside, Ca 92057 | ||

Well guys I think I have my shifting problems fixed, at least I hope! When I added the stator and rotor this year I did not adjust the pawl, I just threw it and expected it to work! I completely forgot about having to adjust the pawl. I think that is why I have been having problems shifting into fifth. So I tore down the primary today and adjusted the pawl.  While everything was open I checked to see how the magnet that I used JB Weld on was holding up. I marked it with an x and as you can see it is doing fine.  I had this thick like paste in the bottom of my primary last time I opened it up and was thinking it was the new clutch, but it's there again. It is not as thick, but it's still there. I will have to make sure the clutch is adjusted right on and wait until I am in the primary again.  I checked all of the clutch discs and plates and everything looks fine.  I also ordered my playback tachometer yesterday so hopefully it will be on the bike for the July race. Scott | ||

Well I finished up with the primary today. I replaced these parts.  Here are the three new ones, I didn't get the small spring until after I had the primary back on.........so I have it next time I open the primary up. Notice my big spring is kinda messed up?  Here is the new detent plate on top of the old one. See how the valleys are a bit deeper, this should help.  Here is the spring I did not replace, but bought. I will change it out next time as mine looked ok.  Took the bike up and down the street today for a few very low passes just to see if I could get it into fifth. I still need to change the angle of the foot lever, but I was able to get it into fifth with no problems. There was once or twice I wasn't sure but once I started counting the down shifts instead of the up shifts I was 3 for 3! So hopefully between everything I checked, replaced and adjusted we won't have any more issues. Scott | ||

This video is me screwing around with the shifter as I take off on the bikes first pass in May at the 4:55 mark in the video. http://www.youtube.com/watch?v=HwMxf7klrks The 5:00 mark of this video you can see the bike at full chat going through the traps 167 at at the June meet. http://www.youtube.com/watch?v=UmTr1SXVK1Q Scott | ||

Took the bike down to the dyno today to make a few test passes and make sure the bike is shifting correctly. All seems fine and it shifted into fifth with no problems, I did however find neutral a couple of times going from first to second. While on the dyno my coil bracket broke, which caused my wires to go tight and they rubbed through the iginition wire and caused a short and fried one of my switches. After a quick repair so we could continue on the dyno we made a few more passes at which point I noticed the intake had loosened up again. This is when we noticed I had initially installed the gaskets on the intake wrong. Bonehead move on my part!! Back to make another pass, the bike is running fat until about 5500 rpm and then it starts to go lean all the way to redline. So a change of the main jet to fix the problem as all we are really worried about is the top end power as my bike should never see 5000 rpm except for at take off in first gear. Change the main jet and it is still fat but we are getting closer, I go to change to a larger main jet and the dam thing will not come out. I believe the head on the jet got partially stripped so the carb has to come off. All in all I am happy even though I had a string of bad luck and I had some things pointed out to that were done wrong. I learned a lot from someone who I hold in high regard. We made seven passes and all of them were with in a 1-2 horse of one another, so the bike was very consistent. Peak horsepower was around 124+ and torque was 99+. This is good as we did not finish with the dyno passes as I need to remove the jet and fix the other items. After the repairs are made we will make a few more passes in an effort to get some more power out of her. Scott | ||

Here is my cracked coil bracket.   And the bastard jet that kept me from finishing the dyno runs.  Here is the carb with no mounting bracket.  And here it is with the new bracket to support the weight of the carb and to help with the vibration.  New tach has been mounted in it's new location, wiring will be done later in the week.  And as if things haven't been fun enough in the past week with the bike. My bike has dual plugs per head and the center one on both heads came out like this. I know use anti-sieze.......it's amazing because I own a tube of anti-sieze and I didn't use it and am going to pay the price.  | ||

After repairing everything on the bike after last weeks dyno run, I went back for more!! The bike made some more power with some more carb changes. I still have not touched the timing, I should make a few more passes prior to Bonneville to dial in the timing and one more jetting change. The final numbers were 128 hp and 101 ft lbs tq. I am pleased to say the least!! We were going to make one more pass to dial the A/F a bit more and on that pass I couldn't get from first to second, only to neutral and back to first. I was hoping to finish that pass as I felt it was going to put me at the 130 mark. Here is why I couldn't shift.....this cast POS!  So I bought a new shift arm from Al at American Sport Bike.  I took the bike for a spin after the new arm was installed and I still couldn't get into second...........hmmmmmmmmmm..........time to open the primary up again. The metallic oil scared me..........  The starter gear took a few thousands off of the shifter pawl lever.......   Here is the problem, the snap ring holds the washer against the brass bushing which is held up to the back plate of the pawl.....my washer and snap ring were setting in the back of the machined hole in the cases not attached to the pawl shaft. Here is the pawl with the new parts installed and the old ones on the book.  Here is where the pawls brash bushing slides into, the backplate is then bolted to the case via the two studs.  THIS WAS MY SHIFTING PROBLEM ALL ALONG!! I am glad I found it on the dyno and not at Bonneville!! While the primary was open I took the gear set out for some investigation to ensure everything was intact and in proper working order. I took it to a fellow racers shop for examination and a clean bill of health. All is well with the gear set with the exception of a little wear on the second gear dogs. On a side note this Sunday's race at El Mirage was canceled due to standing water on the course. This weekend was going to be a final tuning pass for me prior to Bonneville. Now I will have to make my final check out pass on the Sept 14th at El Mirage and then we are off to Bonneville on the morning of the 15th. I am glad all of this recent stuff has happened when it did, instead of at Bonneville. Scott | ||

Got the transmission and primary all back together along with the new shift lever. Took the bike up the road yesterday and as soon as I shifted into second I knew my problems were gone. I had no problems from 1st-5th, I think this problem is behind me now. Scott  | ||

Sweet. I've broken a couple of those cast shifters, too, but I just buy used ones off the take-off table at my local shop. That obviously wouldn't do on a machine of this quality! How did you fix the coil mount--reweld or build new? Thanks for letting us follow along! rt | ||
| Isiahstites |
Road_Thing, I re-welded it for a the run at El Mirage that got canceled. I will be updating the bracket in a stronger configuration prior to going to Bonneville. I am glad you are enjoying the story. Scott | ||

After dinner this evening I decided to tear down the top end to check everything out and to repair the center spark plug thread on each head as well as properly index the plugs prior to going to Bonneville.  Here is the rear head, everything looks good to me but, what do I know! I expected more carbon build up, it is minimal.  Here is the front cylinder and piston, looks like all of my measurements for piston to valve clearance were correct. The eyebrow indent you see was from when these pistons were in another motor and I needed pistons for Bonneville last year.  Here is the rear cylinder. Anyone know what that weird spot in the middle of the piston is??  | ||

After taking some time of to spend with my new baby girl Sienna I am back to work! Bonneville is a month away and I want to be ready in advance. I chased the threads of the two bad spark plug holes and this is what I got out of one of them. It appears worse than it was and the plug threads in smoothly now and is rock solid. These holes will be getting time serts next year when I tear the motor down to check tolerances.  Plugs indexed  I didn't forget the anti-sieze this time.  I also started the oil bleed-off.........here is the pump in stock form.  And here it is with bleed-off partially installed.  I have the motor back together and will continue to button everything up. This was donated to me and will help a lot with the tuning of the bike. I can now install the data logging system.   I have also been beefing up on my gear....   More to come later...... | ||
| Reepicheep |
Excellent! If you still have the rockerboxes off, you might want to update that oil pump drive gear. It'd be a dumb thing to ruin a Bonneville trip over. | ||
| Road_thing |
Tell me about the oil bleed, please--what's it for and where does the bled off oil go? rt | ||
| Isiahstites |
Reep - The oil pump drive gear that is behind the cam cover is an updated new one that I installed when I built the motor. It probably has less than two to three hours of run time. Road - I will post more pictures of it finished when I get done with the install. Basically it bleeds off excess oil at high rpms to keep the motor from wet sumping. This should be good for some more power as well as the flywheels will not have to cut through any excess oil. Scott | ||
