Hi guys haven't been here long, but I'm working on a winter game plan to pump up my 01 929. had some ideas but my reserch is coming up short. I can't seem to find articals on what I'm looking to due. so I was looking for a little help. if I'm thinking of something stupid please shout it out.
1. Power commander
2. 2 up rear
3. port and polish the head
4. 3 or 4 angle cut the valves... maybe even go Ti valves
5. degree the cams for opt performance... is this a common issue?
6. 954 swing arm.... is it a direct fit?
7. I've heard a full system is not the way to go since the servo actually helps with the power
8. any mods I can do to the throttle bodies?
9 K&N air filter
10. ignition upgrades? do they make such a thing
11. better clutch
I'm trying to bump it up with out getting into the motor and spending a ton on new cams. all the work I'm planning is relativly cheep compared to cams and pistons.... if it will all help I should be able to bump the power up to around 145hp at the wheel.... I may be wrong is saying that. but thats why I'm here asking guys that have doing this for longer than I have.
Any help at all is greatly welcomed. thanks
2. Good if you're already one down on the front.
3. Good but would be of more benefit with cams.
4. I wouldn't bother with more than a three-cut on a road engine. Ti valves are good _if_ you run lighter springs or run higher redline, otherwise there's little if any benefit.
5. I doubt degreeing is going to give much improvement on a stock engine with a fresh camchain.
6. As far as I know yes, but I'm not aware that it improves the bike, apart from saving perhaps 200gms weight.
7. HTEV is useful if you spend time below 4000RPM perhaps as it robs power from the topend. If you enjoy 8000RPM+ a full system is the way to go. Certainly if you're chasing a big peak number you need a full system.
8. 954 throttle bodies work well but again, expect to lose midrange.
9. K&N is junk. Go OEM or BMC.
10. Probably but I can't see any value in it for a stock engine.
11. Why? The clutch should be just fine.
If you're going to pull the head and throw hundreds of dollars at porting, valve cuts and even more still at ti valves and springs I'd recommend cams as well. In fact, I'd go cams instead of removing the head at all if you're working within a budget.
A full system and cams should get you your 145hp depending on what you're starting with on that particular dyno.
