Has anyone ever experimented with the cam timing an a wolverine? I need to know what the best all around intake lobe center is for thet engine with a stock cam. I checked mine and it is at about 111degrees which is quite high.I would like to try 106-108 but would like to know if anyone else has done this yet.As yoy would know if you understand cam timing a low lobe centre gives you more bottom end and a higher centre gives you more top end . I have an 82GS1100 that I rebuilt from the crank up . When I first put it on the road it worked good but had no bottom end power under about 4000rpm. I checked the cam timing and my intake cam was at 103 degrees and the exhaust was at 116. This was way off considering both cams are supposed to be at 109degrees. When I changed the timing I couldnt believe the difference. The bike pulls hard from 2800rpm up to about 6000 then it will lift the front wheel about 4 inches off the ground and launch until it hits redline.Quite a rush in1st and second gears.
Saves on front tire wear anyway. Back to my question. Does anyone know the ideal lobe centres for the intake lobe on a wolverine . I know I cant change the cam timing offset because it is a single overhead cam. I just want to play a little.

 

Do you know the stock Wolvies cam Lift and duration numbers? They'll be close to the warriors I bet.

My 1994 Warrior cam was a .380/.382 and I went up to a .430/.430 and longer duration on the 400cc stroker engine build-up. Nice low end torque, strong mid, and high reving top end. I love this cam.

 

Funny you ask that..I'm in the middle of a cam swap myself. I posted a question under performance mods that maybe you can answer. As for yours, I think the only was to do it is to skip a tooth on the sprocket either way from TDC. Thats the only thing I can think of. I wouldnt mess with timing though, could lead to some serious damage.

 

NO Boomer I,m not talking about jumpimg any teeth either way this would cause problems.One tooth is about 20 degrees. I,m talking about an adjustable cam gear. You gan get them from Alba Yamaha. Or you can do what I did and this is to widen the slot in the gear a little then re-weld it back when you find out where it should be . But the adjustable sprocket is easier. A lot of people are intimitated by cam timing but all it takes is a degree wheel and a dial indicator and some know how. Most people dont realize that any thing that is mass produced is sublect to a lot of variances. Read my origional post about my GS1100. When I checked the timing with a degree wheel you would think my timing marks were off. But they weren't. thats how much variance there was in that engine . Also it had a new cam chain. After I altered the timing on my GS with slotted sprockets, It made ita totally different bike to drive. I know it works.

 

 

 

if you do decide to bump it ahead a few degrees,let us know where you were at, and how far you advanced it. I used to have a drag car & was always messing with cams & cam timing, but never really thought about it with my wheeler.I sure would like more bottom without alot of mods or noise.
