What Did I Just Buy?

[ericr1]

From what I can tell it is a Baja MB165, this is my first Mini Bike fixing it up for the kids to ride around the yard. Before I go purchasing parts can someone please confirm model. Also can the engine be upgraded? Thanks for the replies and was glad to find this cool forum.

Welcome! Cool bike!
That is a good motor ( a classic with many upgrades ) and super easy to work on.


Edit: just noticed it was a 3.5hp,thought it was a five., so can still pull some decent hp from that.

Just found this on the engine

Looks like I need an air cleaner, any ideas?

 

[ericr1]

The stock engine on those bikes is a 5.5hp or 6.5hp Honda clone. You now have a 3.5hp Briggs flathead. Also stock was a bolt on jackshaft that provided a 2:1 reduction. You need that jackshaft or you will burn up that clutch. You can get the jackshaft for $60. I'd get a Predator for it will you're at it. In stock governed form, these only do 20-25mph but they get there pretty quick.

So if I install this

Can I go direct drive or do I still need the jackshaft?

Thanks for the replies so far

 

[rmm727]

You'd still need the jackshaft or get a TAV. Your clutch is probably a 10t and the rear sprocket is a 50t I believe and that doesnt fair well with a 19in diameter tire.

OK going to purchase a predator 6.5HP 212CC from Harbor Freight can some please recommend an affordable torque converter, I see several on eBay just not sure what model I need. Thanks

Just look for one with a 3/4" driver and the 40/41 sprocket

Gas Cap

Thanks for the comments so far

The guy I bought this from said the gas tank was from an Harley Sportster, he modified it to fit, does anyone know where I can get a gas cap for it?

Should be painting this week

 

[rockman96]

That doesn't look right for a normal Sportster tank bung to me... Sort of looks like an early style that someone has 'modified'. Check ebay, but I'm thinking you'll have to weld some new bungs in there.

Found a Cheap Chrome gas cap on eBay, just going to epoxy it in place

Painting tonight, should have some pictures this weekend.

 

[rmm727]

Could always go to a Harley dealership.
