99 M750 Drained fuel into crankcase

TheInsider · October 10, 2013, 11:59:18 AM

Noticed the oil level way high so I sniffed the oil and yep, gas. On these 99 M750's is it the vacuum petcock that goes or is it a jet needle/float needle issue usually? Perhaps both in this case. Im thinking of changing it to a manual petcock either way but I hope I dont have to pull the carbs right now.

Oh, I would like to point out it was half a gallon of gas in 1 day

Well I pulled the vacuum and gas came out. Time to take a trip to Yeager's for bypass city...

Out of curiosity -- what is a good replacement manual petcock for the vacuum one?

I got mine off ebay. Cheap yet effective. Brass body with barbed fittings and a red knob.

This looks cool:

Haha why does it say not for engines over 300cc, 5/16 line is enough our bikes...

I have no idea why it states engine size, it is simply a quarter turn valve open fuel flows, closed no fuel flow. OEM fuel line size on our bikes is 5/16, most are 3/16. This petcock will allow more volume than your bike would ever want.

I also installed the Motion Pro on my M900. No problems!
