Ok, here's a good one. I recently noticed my v-boost servo wasn't cycling when I first go to start my Max so I was gonna do an oil change and try to trouble shoot it yesterday. I changed the oil and took it out for a ride to warm it up, check for leaks, etc. On the way back home, I pulled up to...

Once again I stand before the elders, seeking their guidance. :biglaugh: Last year I built a 1260 with an approx. compression ratio of 13:1. The pistons were MTC 14:1 pistons but I had to have the valve pockets deepened for the cams I'm running and I had some metal removed from the domes. Fast...

Does anyone know what the Vmax side covers are made of ? I sent them to Jet-Hot to be coated and they told me they were aluminum and were too thin to be coated with their product. They said that they had to get them really hot to cure the coating and they might melt. I saw a listing somewhere...

Can anyone tell me if Yamaha Venture carbs will interchange with Vmax carbs. I have a 1986 Max. Thanks.:ummm:

Well members, I'm happy to report that I just got back from my 1st ride on my '86 Max after a ground-up overhaul including replacement of the cases themselves due to a spun main bearing. I bought it a year ago, stuck in 1st gear, but after I updated the segment I found out that it had the 2nd...

I'm kicking around the idea of getting my airscoops Jet-Hot ( aluminum ceramic ) coated as an alternative to the labor intense polishing and the expensive chrome plating, but after contacting Jet-Hot they want me to sign a damage release because they use heat to clean/ apply their coating. I'm...

O.K., it's time to consult the experts! I'm at the stage of my build where I need to check valve to piston clearance and I'm wonder what is the best method? Im running MTC 78mm, 13:1 pistons and Web cams grind#227-0.383 lift, [email protected] duration, 276 advertised duration so I want to make sure...

Can anybody tell me the differences between the older 1FK-81410-11-00 stator vs. the later 3UF-81410-10-00 version and wil they interchange? There is a sizeable difference in price through Yamahammer.

I recently found myself having to pull the flywheel off my 86 Vmax so I thought I should share my experience with other members who've never done that job. After breaking my generic harmonic balancer puller I used a 7 ton capacity 3-jaw puller to finally get it off. I've never came so close to...

I'm doing a ground-up rebuild and I have a question about shimming the middle gear drive. I followed the procedure in the manual which was easy and straightforward in establishing what shim package I will need. I'm just wondering what I'm supposed to be accomplishing. In the grand scheme of...

This a good one. I'm doing the oil pipe o-ring job today and I appear to be missing the fastener that goes through the rear-most pipe coming off the main gallery supply pipe where it attaches to the engine. It's the pipe that looks it has a banjo type fitting on the end of it. Does anybody know...

I dropped the oil pan on my recently aquired '86 max to recover a shift drum pin today. The pin was exactly where another member said it would be, in the oil pump pick-up. I also recovered the missing screw for the input shaft bearing retainer, it was in the bottom of the pan. How that stuff...

I just bought a '86 with a Hindle 4 into 1 exhaust system on it and I was wondering if anybody else a set-up like that and what tuning it took if any to get the most outta it. It sounds great but I had to address a segment problem so I havn't been able to ride it and the guy I bought it from...

First of all, Thanks for allowing me into this forum and allowing me to tap into this Fort Knox of knowledge. I bought my first Vmax yesterday after years of wanting one. It's an '86 with 26k miles on it. The poor soul I bought it from let someone take it for a test ride and the guy brought it...
