Hey Everyone, I have a 99M2, and I have two of the most common upgrades, the pipe (V&H) and the airbox (Force Sidewinder). The pipe is great, added some push and has a great sound. The Force has also been good, looks great, but I think I lost a little initial pull over my original gutted airbox with the K&N filter, but it is not too noticeable. (I also did the mod reccomended about filing a hole to a bigger size). My question is, what is the next reccomended mod to get some increase in power, bang for the buck. Am I looking at increasing the engine size? Different headers? (I have the Stainless 2000 headers) Any ideas welcome. Thanks, The Setta  | ||

Setta, Based on what I've seen and heard, spend your next dollars on a good dyno-tune. Timing and jetting. Next on the list would be fairly external mods such as carb, cams, and next up would be head work. After that it gets nitty-gritty as you open up the cases, pop off the cylinders, and crack open the wallet. Define your destination, then map out a route to get you there. | ||

Setta, Lightening cams are a cheap way to get some HP near redline. See Aaron Wilson's posts in the knowledge vault under dyno chart listings. Aaron posted a chart on Apr 27. With Lightening or SE1 cams the M2 had 7 more peak HP over the same bike with stock cams. I'm a great believer in having the heads done. I gained about 20 hp by having the heads done & a dyno-tune by Cycle-Rama, SE1 cams, & a Mikuni 42HSR carb. The Mikuni probably did the least in obtaining increased HP. But doing the heads really fattened the mid range. My dyno was posted on May 10. I'd do some exploring on this website by looking in the knowledge vault & seeing what has worked for other people. The Force intake is the best as far as I'm concerned. You may also want a full exhaust system, maybe D&D's or the Buell race kit. Dave Frye | ||

M2cyclone00, What is involved in having the heads done? Was it an expensive process? I like the idea of getting some head work and adding the lightening cams if it is pretty reasonable. I appreciate both yours and Mike J's help, thanx. Michael | ||

Check the head prices offered by our sponsors. | ||

We pulled 85 RWHP and 85 Ft-lbs on a 'fairly' stock (about $200 worth of mods). Adding the cams picked us up to 90 HP. Head work and Millenium cyls (basically the Nallin Kit) and Lightning Cams had us up to triple digits. An 88" kit (same heads and cams, split cases S&S bottom end) got us over 110 HP and 105 ft-lbs. Now, in less than 2 weeks, the 88" 4-Valve setup will be complete (dual carbs, anti reversion pipes)   | ||

Dynodave, could you expand a little on "anti reversion pipes" please? | ||
| Msetta |
Ditto for me. And thanx for the input. The Setta | ||

Setta, heads usually run between $500 to $800 depending upon whether you go with oversize valves or not. I stuck with stock Thunderstorm sized valves. Those prices will include new valves, guides, seals, re-seating. Tear down & re-assembly is extra. It's a good idea to polish the intake along with the heads. Pammy, I can't get to Cycle-Rama's website lately. Different address? | ||

M2cyclone00, So what can someone expect adding headwork to an M2 with a Force and pipe? I prefer my stock cams as opposed to top-end punch. | ||
| M2cyclone00 |
Leeaw, I've got 94.5hp with mine. But it does have the Lightening or SE1 cams. I would guess high 80's? From what Aaron showed on his dyno, the Lightening cams are good for about 7hp near redline. If you stick with the stock M2 cams or Lightening cams the mid-range will be good. Mine has peak torque at only 4000rpm, about 90ft lbs & by 3500 it's already in the mid to high 80's. I like a strong mid-range, so I haven't gone with bigger cams. Dave | ||

On the bigger motors, the SE1 cams give awesome mid and low RPM torque and only lose about 5 hp to the SE2s at the extreme upper end. Cruising at 1500 RPM is no problem. By 3000 RPM you are over 90 ft-lbs and at 3500 its over a ton; staying over 100 ft-lbs up to 5500 RPM. The 4-Valvers will maintain that torque band right up to red line. The anti reversion pipes are made by having two pieces. A short straight piece goes to the port. The second piece has a flared out section about 2" long. It is welded to the short straight piece such that there is an overlap, the smaller pipe protrudes about 3/4" into the flare. This is known as a Bernulli Valve. Outward pulses see the smooth flare transition and maintain laminar flow, but the inward reversion pulses see the discontinuity formed by the protruding port piece and are broken up. This improves the cylinder filling efficiency and the result is more power. See the MaxTEngines.com site for more info. | ||

This is all very good stuff. I want. If I only wasn't so broke  How much difference is there between similarly ported Lightning vs Thunderstorm head bikes? Anybody know? | ||
| Blake |
Dynodave, Cruising at 1500 rpm? Really? Did you mean 2500? | ||
| Leeaw |
M2Cyclone, That is impressive for a reasonable outlay. I have three little mouthes to feed and little to spare, but I think this is a winter project in the making. | ||

Thanks for the feedback everyone, I think upgrading the cams is a good way to get the power up, just trying to find some pricing. Blake, I would use our sponsors but I am in Canada and I don't know if they can sell/ship across the border and how much more they will cost with our nasty exchange rate. Getting head work sounds ideal, but I would have to investigate the experitise in my area and the cost. I will look into it. On a slightly different note, have many people removed the fender and the belt guard on the back of the M2? Might have a better naked look without all that black plastic, but how will the electronics above the seat be affected? Did anyone feel the need to create a makeshift cover under the seat? Any concern about not having the plastic protect the belt? Thanx, Setta | ||

MSetta, E-mail me about the head work. I know of a contact in Toronto that may be able to help. Bill | ||

MSetta, I've heard good things about the head work done by Head Quarters in Ontario. www.head-quarters.com John |
