Kind a like battery is running low voltage. Then power off and...

    An upside-down, original design streetbike engine, mounted in a one-off (well, two-off) frame, and yours for a reported $300K! Made in Italy, and like nothing you've ever seen as a motorcycle, I'd bet. http://silodrome.com/nembo-motorcycle/

    98 V max won't crank

    So I took the battery out of my 98 v-max last fall, charged it and put it in my heated basement on a wood block. Took it out last week, charged it at 2 amps overnight and threw it in my v max. Went to start it, lights came on, but no vboost sound and nothing else happened. Made sure it was in...

    Stiff Crank

    Could anyone tell me how much torque it takes to roll a crank with the spark plugs removed by the end that is under the cap on the stator cover? Mine is very tough to turn.

    Intermittent no crank issue

    Hey guys I hope this question hasn't been asked too much but this problem is really starting to get on my nerves. My bike is a 90 model that I just bought a couple months ago.

    left side crank case leak

    I noticed the crankcase cover on the left side was dripping oil. I ordered and replaced the O-ring and the large gasket, but still have a oil leak, and when I pull the cover off it looks like its coming from the center area. Does anybody have a suggestion or recommendation of what else to check.

    crank case breather

    I just bought my vmax not too long ago and I noticed it has 4 K&n filters and the oil cap has a breather hose going up to a plastic canister and it feeds into the filters. I was wondering what this is for because most other vmaxs don't have it and I kinda wanna take it off if i can.

    Anyone got a pic of the crank gear timing mark?

    I can see a timing mark on the balance shaft, but I can't see one on the crank gear. The genuine and aftermarket manual I've got don't have any good pics. There is white paint on one of the teeth. I scraped it off a bit but couldn't see an indent.:ummm:
