good job Alex but the engine does not sound very healthy.


what is wrong with it?


are you using the 35 gear on the clutch?

 

[forist]

very nice work, sounds like it might have a air leak or not getting enough gas.

 

[Alex]

Jea its a 78 clutch and 35x25 ,and now ,that is my prob ---airleak or not enough gas ,i screw the low idle a bit out and i run great but after some laps the engine make this sounds like mohhhhh mohhhhhh

 

[forist]

Did you vent your gas cap ?

 

[forist]

just watched it a few more time sounds like a air leak. I had A 30.5 that did the same type of thing/sound.

 

[Alex]

yes ,i ve made a tankspot with 3 fuellines and the 3 rd line is open back.Look to my album

 

[Alex]

airleak????????where was yours on 30,5

 

[forist]

Mine was a crack in the head but it could be the plug needs to be tightened or head gasket cracked or even the gaskets on the carb. Some guys use WD40 (I think) and spray it around the gaskets to check for a leak. If its not WD40 someone chime in plz.

 

[forist]

I looked on your albums and only see 2 fuel lines. You can check for gas cap vent prob by when you run and it starts to make that sound, open the cap and listen for a hissing sound that is to much pressure building up in the tank. You will have to vent it.

LMAO airleak or not that thing has tons of power. He's drifting it at what sounds like 1/4 throttle. Nice work man. I got a hold of another TT so guess what's going in it?


46cc with a prototype 2 speed


P.S. We finally narrowed down the 2 speed to the best performing design. You guys are gonna shit when you see this thing. Hopefully, we'll have all the parts in from the shop soon.

 

[Alex]

Hey guys i ve found the prob it was a carb ,no ideal why ,but i ordered second 46cc and switch the carb to my ,and lads the engine is the beast ,the video will go on sunday or saturday.


Greats Alex.

 

[grf]

cannot wait for this video. well done again alex

 

[DemonRC]

I really wanna see some video with it running 100%. Doug at ESP said he got them to hit 13k RPM with minimal porting back in the day. With all that torque it outta be a hell of an engine.


P.S. Doug wasn't sure if the CY engine plating fixes ever made it to the 42/46 series. I was the reason he stopped porting on these a few years back.

That's sick! Obviously has some crazy torque.

 

[rcgasser]

That is insane!!!!!!!!!!!!!!!!!!!!!!!! Nice Job!!!!!!!!!!!!!!!!!

 

[SerratedPHX]

looks bad ass! But I think we need stronger options for the drive line. Im always braking axles and the cups. I really sick of it and its getting discouraging.

 

[DemonRC]

Runs great! Can you get some pics up of how it's mounted in? I'm sure alot of guys here would wanna make the move.
