build build build... a nice roller cam do they make roller cams for bikes? some new pistons, maybe a 1lb bottle of nos, a 520 conversion, full exhaust system, do they make a turbo or supercharger? see if you can find a 929 thats being raced and see what mods they have.

i'm trying to decide the same thing you are, and i really like the 929 so i'm thinking i might build it up.. try and get around 150-170hp or so out of it. so you should build yours up so i know what and what not to do.

edit: you should probly get how much all that would cost first and see if its even worth it.

 

I found a 954 motor around me and i think that i might try to do it. Who knows........

 

is there really that big of a diffrence between a 929 and 954 in power? you might get just as much power by just adding a full exhaust and some other mods.

 

i think the actual difference is 8 hp. not sure though. I was originally going to buy another 929 motor and build it but i found a 954 in town. Shipping is so much for crates and plus the 954 motor has less miles than the other. i am still reading around about it. so who knows

 

on ebay there is a set of moriwaki cams brand new item # 4619234928 , i seen someone also who has a port and polished head for sale that would work great with those cams , get an htev eliminator , power commander , kand n air filter ull be eatin the new bikes for breakfast. Also if you go to www.erionracing.com they sell engine parts from there 929s some used and some old/ new stock from there race bikes . If u grab up that stuff im sure u will have one seriously insane 929 .

As far as the 929 and the 954 go stock bikes on the quarter mile the 929 - 10.3 at 139 mph the 954 - 10.8 at 137.5 mph so the 954 isnt neccasary a faster bike although its torque is 77 ft lbs at 8900 rpm and the the 929 is 72.3 at 7500 rpm u will get alil extra power comin out of corners with the 954 , all u have to do with a 929 is change the the sprokets from stock 16 tooth front 43 tooth rear which has a final drive ratio of 2.69 The optimum ratio is 15 tooth front 45 tooth rear which has a final drive ratio of 3.00 and instantly u got the 954 beat from every angle

 

awsome link! has everything you would need. also about 10x more expensive then rebuilding a car engine

 

hahaha yeah its not cheap but if u wanna be faster then the other guy u have to pay to play , but if u think about it the bikes that stuff came from was worth about $200,000 so really ur getting a good deal, lol i know a guy selling volocity stacks , aluminum brand new that are exact copies of erions for about 250 a set , good deal considering erion used ones are 400,

anyway if u run into money (alot) and decide u wanna fix her up thats the place to call

Can you use the stock link chain with 45 rear and 15 front??? thanks

 

Hey, ericmxzx440.
I can only tell you my experience, which I posted some weeks ago in answer to another question -

I got my 929 with stock 15 front and a Spocket Specialists 48 rear. According to my manual, 42 is stock rear, but I read somewhere prior to getting the manual that stock was 41 rear. So I ordered a 41 rear from Spocket Specialists.( I guarantee some of you are already laughing...)

That's when I realized - when you shorten a chain, you have to shorten it by at least two "teeth", so to speak. So you can go from 48 to 46 or 44 or 42, and so forth and just shorten the chain by a link ( two teeth ) at a time, and not have to adjust the rear axle, and keep it in the "good zone". In my case, I had to compensate for the "Odd" rear number of teeth by either moving the axle forward to where the tire almost touched the swingarm, or rearward (which I did) to where the wear indicator is just at the aft limit ( indicating a worn chain, even though it isn't worn).

If you can picture this, if I were to go to a 16 front with the 41 rear, it would pull the axel forward again and the wear indicator would be where it belongs.
