well if your riding it on the street get rid of the whole jack shaft assembly, flip the clutch and run a chain straight back to the wheel. top speed will be more like 55mph but you will lose torque, the other option is to install a torque convertor and raise up the engine about 1/2 to an inch.
I just added a small spring to pull the throttle closed so it didn't take off but it was hard to go wide open, it's unfortunate these Colemans come with such a poor throttle assembly
They are not poor throttle assemblies. The Honda design has been around for more than 2 decades and has been used successfully on 10's of thousands of engines including many varieties of clones like the Hisun engine Coleman uses. I have 6 clones including 2 Hisuns and never had a problem with any of their throttle linkages. The Hisun engine is a very good clone. He mentioned springs in the video. It may be possible that when the engine was completed someone was using the wrong spring that wouldn't allow the governor to pull the throttle on the carb back to idle. That would be human error not a problem with Honda's linkage design.
I feel this solution would be problematic for the governor inside the engine as it uses centrifugal force to move the arm and will be unable to, causing additional resistance on the cranks and governor gears inside the engine. A better solution with still not opening the engine would be to completely bipass the governor arm and route the throttle cable straight to the carb. I plan to do this and will make a video if it works.
This "solution" and the one you suggest are both Jerry rigged. The real solution is to open the engine and remove the governor mechanism or the drive gear from the crankshaft.
@@Deucealive75 if the governor arm isn't attached to the throttle is doesn't change throttle and does not harm engine... Been ripping my coleman with a governor bipass for months now and it runs great no issues
@@coreyconachan2553 That's cool. I'm just saying removal is the right way. There are many (not me) who are concerned about a plastic governor gear spinning must faster than it was designed for. Not to mention a plastic cam gear. The guy in the video was spinning to at least 7000 RPM. This is nearly double what the engine was designed to run at.
@@Deucealive75 yes that is true, I honestly don't care if I harm my engine, I want to swap a predator anyway, but this engine has taken quite the abuse and still works great
@@underdoggrisingent.4322 you might need a tighter return spring or add another spring for your throttle return hold that little metal stick that moves when you move the throttle in the closed/off position and see if it still does it make sure the throttle isn’t engaged at all and if it doesn’t move you know your problem
@@peytonismyname9258 I remember this video. What he's doing here is not a good idea. These engines were not designed to spin this fast. Works nice initially but the rod will wear out in the long run. The way to go is a billet rod if you are going to run at higher than stock RPM.
ATTN GO POWERSPORTS. This is the correct exhaust that I ordered, you sent the wrong one for who knows what, and refused to send me the correct one. You told me to buy your silicone sleeve to fix my issue. AVOID GOPOWERSPORTS.
How did u fix ur idle speed issue
Did u ever fix ur idle speed issue. Mine is doin the exact same thing.

cool
How’d you fix the problem that you had where it took off when you turned it on? Same things happening to mine and I would really appreciate the fix.
Still need help?
@@isaiahjacobs2962 yes!

Wow. If your GPS is correct on the 40 mph you were running 7200 RPM. Pretty risky.
with the 18lb valve springs he can probably push more rpm.
