Hey everybody I've got a weird problem with the bike. Couple seasons ago motor took a dump so had it rebuilt with a nhra 515 kit and wasent able to ride much last year with work. Anyway I put it up for the winter around October of last year and just got it out few weeks ago put gas in it and started up no problem after few miles of riding the oil light came on and started making a ticking noise. Pulled over and checked level it looked good. Rode it home and changed oil thinking it.might have been thick from sitting for winter and filled it started up and same problem. I guess what I'm wondering is what could be causeing it cause I really don't have money to put it back in shop.

Have you changed your filter?

You may need to check your oil pump drive gear then. They're known to be a weak point on a Blast engine.

It might be the pump gears as jetlee mentioned. It could also be a plugged oil line or gallery, possibly from debris such as gasket material, metal, etc. when the previous engine died. Also could be a bad (or plugged) check valve, which you can verify with the filter removed.

How could I check for plugged and when it was rebuilt they went through every thing from crank to rebuild head

they went through every thing from crank to rebuild head
I doubt it. They tell you that to make you feel all warm and fuzzy so you pay more. They're not going to thread every oil passage when all they need to do is throw on a new jug/piston/head and charge you 12 hours for a 2 hour job.

Alright everybody well I think I found the problem. It looks like oil pump locked up somehow and sheared the gear on the crankshaft. Question now is can I replace just the gear or does the entire crank need replaced .

Never mind last post found gear was the oil pump drive gear. Thanks jetlee now to get a new one ordered
