4stroke 50cc
Stowaway,
I hear ya on the dui. Thanks for raising those questions about your carb and choke. The fuel/air mix screw on my honda gxh50 only has a 1 o'clock to 5 o'clock adjustment and i have not found it to be especially useful, but I will try again. i have been using my motor for the last 2 months regularly and probably have 100 hours on it with the larger sprocket (as i recieved 2 sprokets with my kit as well). I like the Honda, it gets me to about 35 mph before topping out on my heavy cruiser.
However, my motor developed a tick at about 50 hours that i belive is valve clearence adjustment. the tick is clearly related to valve or piston movement and is one of the signs that clearence needs to be adjusted (re: operatos manual). apparently, the valve clearence adjustment is part of the standard adjustment of a 4-stroke, as i found the specs for clearence adjustment in both the honda gxh50 operators maual and my honda xr250 service manual. I have ordered the gxh50 service manual (33$ from
www.helminc.com) to assure that i fix this problem correctly.
Which gearbox did you get. it looks like the new gearbox from grubee, the starfire, which is supposed to be quieter than the old one. do you know if you GB is a grubee, or another brand. Does it have a high pitch whine when you get up to higher rpm's or is it quiet.
Im posting a new thread under tech / mech with pics of my motor before i tear it down this week, check it out.
