03R/Tbanshee Posted October 30, 2009 Report Share Posted October 30, 2009 hey all, im looking to get some more power out of her. i only have fmf fatty pipes and its jetted, dont know what size jets but i will be finding out soon. the bike runs really good but im looking for some more power now. i was thinking next to get some delta vforce 3 reeds, a timing advance key, and shaving the head. now i know i cant go wrong with the reeds but what about the other 2? im not looking to break the bank because i already have another money pit lol. right now i run a 32:1 ratio with 93 octane with these other mods i wouldnt mind running 100 octane all the time, but i dont want to go any higher than that. thanks in advance Quote Link to comment Share on other sites More sharing options...

As far as head shaving, if you are currently stock and running 93octane, your wasting money, and if you just mildly shave your head, your still fine at 91 octane. You need to check your compression after your head is shaved. 130psi and lower is fine to run 91. I have ran 91 at 140, but some advise against it Quote Link to comment Share on other sites More sharing options...

I have ran 91 at 140, but some advise against it whats the psi for a stock motor? and how many thousandths should i take off to get to 140psi? if anyone knows how much to take off for a desirabe psi (say ten thousandths for every 10 psi) that would be great, also how far can you go with a stock head?

jbooker82 Posted October 30, 2009 Report Share Posted October 30, 2009 Dont get a deg key they are weak and can shear off. Get an adjustable stator plate instead. Make sure you use the correct flywheel puller. Dont use a 2 or 3 jaw puller it will bend the flywheel. V force reeds dont really ad HP. They will make for a better throttle responce. Most people shoot for 150 psi to run on pump premium fuel. A new top end, with stock porting at sea level is supose to be 130 psi. If your altitude greatly effects the compression your engine generates. If i was you I would take the money you were going to spend on the Vforces and get a noss head, Then just get some replacemt carbon tec reeds for the oem reed cages. josh Quote Link to comment Share on other sites More sharing options...

Sounds to me like you need to get a port job. Much better gains than the mods you've listed. I believe HJR has an MX option for like 250 bucks if you are on a budget...

jbooker82 Posted October 31, 2009 Report Share Posted October 31, 2009 You might have to go up 1 main but probably not. Generally if your jetted corectly then you need to rejet for adding compression, and timing. Quote Link to comment Share on other sites More sharing options...
