Hi, I am trying to find the correct thicknesses for connecting rod and crankshaft main bearing shells but ran into an issue. For crankshaft main bearings you need the markings on the crankshaft and the outside of the engine block. The first one no problem, the engine mount where the numbers...

I have an 89 Max that keeps blowing the main fuse. Started the other day while riding, I'd put the spare in and it would run for a minute, then POP. Now I can't even get the fuse fully seated before it blows. I've already bypassed the keyed ignition switch hoping it was there, no luck. I'm down...

A while ago, before I pulled my carbs apart, I posted a question. In the end I got some 147.5 mains. I'm doing some carby work now, and it's a little different from what I previously guessed. My '85 has had the 2 150's changed to 152.5's already. (So it has 152.5's in it.) I guess the rest...

I know I will eventually find this with searchs, but there are so many threads on this already even the search takes forever. I finally got all my parts to put on the Marks and my Morely jet kit. Of course it is the weekend before Easter and I am out of town this weekend, but I took Monday...

Does anybody have a Vmax carb apart ? I'm tying to find the head diameter of the main fuel jet. It's either 6mm or 8mm - I'm thinking it's probably 8. I'm looking at jets on this website : http://www.pjmotorsports.com/mikuni-jets.html The paj2 is jet part number N102/221 with the 6mm...

Anyone got a spare or know best place to get one?

I have a set of factory pro needles i would sell or trade. Im in need of some good carb boots mine are cracking or stainless front brake lines or new front brake pads for 1993 and up or $50 tyd I have a set of 155 jets, and 157.5 jets $10 each shipped

I have done a few things to my VMAX(not like some of you crazy fools lol) but nobody who doesnt own a VMAX even notices lol. I was even parked next my budy on his 100% stock 07 and a guy says you guys have the exact same bike. I said yes but I have a couple grand of goodies. I guess technicly...

I am still trying to sort out my 91, and I wondered if anyone that needed to change their main jet size can tell me how it ran before they sorted it out. My bike runs uneven and at higher rpms, 7k on up it runs very poorly, but sometimes picks up around 8500 rpms and takes off. Does this sound...

I am in process of rebuilting carbs,and not sure what jets to use. Bike does have supertrapp slip ons,and I live in Chicago not sure about altitude.Now I have 152.5 should I try 147? Thanks

I have an 85 v max with a kerker 4-2-1 exhaust with 2" competition baffle, dyanatek 3000 ignition, Uni filter, and stage 1 dynojet kit. The bike currently has 165 mainjets but came from Kansas which is barely over 1000ft and I live in Idaho at 4500 ft. Just wondering what you think I need to...

are the main air correctors in the sage 7 kit just supose to go in that hole? I dont have to remove that brass thing?

I e-mailed Tim (the VMax Guru) a while back with a few questions on the gen 1 pickup signals. What I was hoping for was an easier way to get a 4 to 8 cylinder tach to work with the VMax. My idea was quickly shot down, but Tim did provide some nice data that I asked him if I could share with the...

With a hindle header and kerker k series can what main jet is suggested?

I currently have a 96 with k+n air filter,stock exhaust,stage 1 needles with the short springs, 150 dynojet mains.I have the needles at the highest setting(leanest).Would this be an indication I need to go down one size on the mains and raise the needles or should I leave well enough alone?What...

All, I haven't done too much work on my Carbs yet, so these are going to be real basic questions. I drilled my stock exhaust and and from my other questions it's probably running a little rich. So it was suggested to drop my Main jets down a size or two... But I still don't have any idea what...

Hey Guys Dont know if this has ever been addressed before but I was reading through the tech manual at work and it calls for different size mains 1&3 152.5 2&4 150 Just wondering if anyone knew why? Thanks Cheers
