I noticed when running my bike on the dyno with the carb stacks off that i am having some pretty bad standoff/reversion i was wondering if anyone has tried torque cones to help this. I know some people have used them for harleys but not with huge results. I think that if i fix this a bit then...

Finaly got her on the dyno at work and did a few pulls and got 128hp and 83tq. I'll try to post graph tomorow. Build is a bored to 1300 10.8-11.1 scr with cleaned up heads done by me, decked 40 thou., and stock cams with stg 7 needles caint remember for jetting lndy filters with stacks and a...

Got everything back together and got her running. So far so good. I love how people ask me if i notice any big power difference from before when it has been a year and a half sine i rode it, and working on Harleys all day riding this thing is just amazing.

I used a degree wheel and piston stop to get true top dead center, which by the way is spot on with the timing mark on the rotor. Intake: Open @ 11.5* BTDC Duration 230.5* Close @ 39* ABDC Lobe center 103.75* Exhaust Open @ 41* BBDC Duration 235*...

I dont have my valves here in front of me and I need to order a valve guide pilot to cut my valve seats I think they are 5.5mm? or if any one happens to have a guide that they could lend out for a neway cutter with a .375 top. thanks

I was wondering if anyone had the smaller cutting heads for the exhaust valve. I have one that will fit for the intake but the exhaust is so small that none of my cuttters will get close. I know that machinest can do it but I cut seats on Harley heads all the time and I know how to do it and I...

Does anyone know what the part number is for the complete gasket kit for the motor and if there is not one does anyone have a list of all of the gaskets, o-rings ect. needed for a motor rebuild. any help would be appreciated. I have looked at yamahas micro fiche and I could do it but if any one...

I am going to be getting my cylinder bored out to fit stock venture pistons in my bike and was wondering if anyone knew what the piston to cylinder space was supposed to be. Found a shop that will bore and deck my case for $300 , not bad I think. They use a cool CNC machine to do most of their...

I was wondering if there was any other forks that are the same diameter as the stock 43mm forks. I was really thinking USD (inverted forks) forks that would work because i know that most sportbike fork tubes. Yes I know that most USD forks are shorter but that is kinda the route that I am...

Does anyone know if the Venture 1300 pistons can be used in the max. It would have to be bored out to 79mm roughly. I know that Sean through Ross pistons can go up to 78.5 but even at 79mm there is still 4mm thickness. and with the 1500cc big bore kits the sleeve thickness is about the same. I...

I was just wondering if anyone has had any experience with this company weither it be from here in the states or in europe. http://www.ignitech.cz/english/aindex.htm I was looking at their TCIP4 ignition. they seemed somewhat knowing of the vmax ignition just slow e-mail reply time. Any help...

metal struts for the rear shocks What size of struts in place of the shocks could be used at the lowest point for the vmax before you would run into problems? Thanks.

Any of the electrical gurus out there think that any of these prouducts could work to make a more programable ignition to use for the vmax. http://www.dynaonline.com/skins/products/sportbikes/dyna_2000/ http://www.dynaonline.com/skins/products/sportbikes/arc_2/ Or any kind of msd ignition...

More like just one chamber right now but I am hoping to have the rest of them done before spring. Here are some pics of my P&P job sorry about some of their quality just the shop camera. Blended the seats, removed all casting marks and divets, unshrouded the valves, polished the comb. chamber...

I know that this question has been asked before but i was just wanting to know about the stock cams timing specs and lifts also the rod length. And also sean you said that thou can be milled from the block is that for the lip of the sleve to make it b/c i think that is gonna be the route that...

I was just wanting a for sure answer that does the motor have to be removed before removing the heads. I was thinking probably so but if not that would be cool. the reason why i ask is b/c I am going to be porting and polishing my heads this winter so i will have some time. I am used to...

I have a sunpro 5'' tach and ever since i have hooked it up it is jumpy so i put a resistor in i think .5-1 ohm helped it out a bit til after 5k then jumpy again. my question is should i just use a bigger resistor or do the mod of using diodes to make a four cylender signal for my tach. with two...

has anyone put a super trapp can on a kerker 4-1 head pipe if so what were the results

even with a 145 mj I am at 11.2 I am gonna try a 140 but I was also wondering if mabie removing the main air jet correctors that the stg. 7 kit came with would help and also how to remove them now. also I do believe that i am having some reversion that is not helping with the filters off i am...

I have been having troubles since getting her going after winter, done the cop mod and went to go on a ride and ran like crap poping backfiring the good stuff came back checked cop wiring, it was good checked plugs and they were good (cleaned anyway). So I start with the carbs shotgun 4 times...
