problem

ok. one month ago i posted a thread about my vboost which i didn't feel it to kick in. my engine is a 1300cc with carillo ,je pistons 79mm. stock carbs. t-boost installed. my mechanic had my main jet drilled so for the first 1500Km my engine untill 4000 rpm run very smoothly.the think is after...

1.) New plugs. Carbs synched after install. 2.) Loss of power, exhaust pop, stumble/ miss. 3.) Tightened exhaust up already, did peashooter. Pulled 4 plugs... ONE plug was all black and wet with what smelled like gasoline. It did not appear to be oil. The other three plugs looked...

OK the other day I posted a pic of my VMAX and someone nticed that I had mounted my exhaust with the tabs on the outside of the back foot peg bracket. see pic below, I looked at several bikes with marks exhaust and noticed that they all were mounted with the tabs behind the rear foot peg...

HI Guys, If you read my post from the last few days you would have saw I was having problems starting my VMAX after the winter storage. I drained most of the gas and added new gas and was able to start it and drive it home about 3-4 miles and when I got home it was ruining much better but...

Got the marks pipes installed, and pulled the slides to shim the needles but I am having a problem. Everything fits fine until I put the small spring and keeper screw in place. When I tighten the keeper screw, it makes the needle tight and therefore makes the slide tight when I install it in the...

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...

:ummm: I'm trying to fix a 3rd gear problem.I've got the engine out and upside down.I took all the covers off and removed all the bolts,but there still seems to be some holding the case together in the area of the clutch.This is the first time I've done this so I don't want to pry on it and...

Ok I am going to try and have some fun with this. I had to have my bike towed to a dealer Saturday afternoon. I'll note what happen, symptoms and what my bike has and see who can people Dr. House and diagnose the problem. Now, the bike was only brought in late Saturday and the dealer is closed...

I changed out my sissybar for the oem grab bar last night had to cut the wires on the turn signals in order to remove. When I wired them back, the signals didn't work (front or back) and now my shifter light doesn't work and my rpm guage only slowly registers and doesn't seem to get above 3K...

Earlier I took apart my clutch to upgrade the shift segment and do the Double D mod. Now I'm having trouble shifting gears. I took it apart again to see what's going on: http://s931.photobucket.com/albums/ad160/yukonerdave/?action=view&current=MVI_9868.flv Any ideas?

Hi there again guys, as on my post below my wheel is still shaking, but now as of tonight I got another problem. Just out of curiosity I opened up the air intake. Well that's when I realized that 4 rubber pieces covering the carbs were not connected at all to it. I just wonder how much of a dirt...

Hi all, I've read some of the threads regarding hot Vmaxs. I'm looking into doing the fan switch mod. I just took it out tonight and in stop-go traffic it got up to about 3/4 - higher than 1/2, but not yet getting red. My overflow tank cap needs to be replaced (it's cracked) so I wonder if that...

Hi all! I'm trying to fix my carbs...and I have a couple of questions... 1- Is supposed to get fuel from needle jet at low rpms? I get some out from 2 of the carbs...the needle is supposed to block complete the jet? could be they are wear and have to change, or maybe float level to high (I...

we just had a huge rain here in texas and ever since then i bike runs fine for about ten minutes and then dies quick and hard, and will not start. the fuel pump also starts clicking before the problems start. then when i try to start it the pump clicks slowly. i dont know if its a fuel pump...

ok so today I checked that I had good spark on my #1 cylinder, and it's definitely a very bright one with the COPs! I then went on to check out the wet floats level as I'd only ever set them dry on the bench when I rebuilt my carbs last year. I took a piece of clear tubing that fitted...

Since I really could not notice any difference whatsoever between Vboost and Tboost, I thought I'd recheck it's fully operational again. Well it is, but not at 3000 rpm, instead at 9000 rpm (!?!) I'm puzzled. In Off mode it's off, nice. In Vboost mode it opens at 6000, nice. But in Tboost...

After much tinkering and frustration my VMAX is finally running like it should The problem turned out to be a bad CDI.....I found this to be very difficult to diagnose the only way that I could eliminate it from the equation was to replace the unit entirely NOW I understand what VBOOST...
