Here are a few initial photos of my FG MT with 'Blue Thunder' bodyshell.
Early on LAST year I bought a 2/3 new Trevor Simpson 2-bolt 28.5cc engine.
This was set-up for Baja use, so I had to remove the clutch, the Turtle Racing housing (sold) and replace my original FG ones.
I've converted the rears to 'Tuning Discs' as well as the front - cables.
The engine is billet TS, TS cooling head, TS reed valve, TS timing cover - limited as I've fitted the kill switch into the cover (don't expect to play too much with that anyway).
PROBLEMS? LOADS!!! But that's normal.
Couldn't get the original clutch off, but I knew a man who can ... and did - sorted!
I had to adapt all sorts of things to fit the rear brakes, but thats sorted, with little hollow bolts meant for push-bikes. (Truck's so heavy I'm considering the hydro layshaft brake, but it'll do for now ....)
I've got the steel pull-start cable installed into .. the pullstart, with billet handle.
When fitting the Kill Switch cable into the green connectors of the Killer Bee in the radio box, I was a little ham-fisted (unusual for me .... !!) and broke off the connecter box!!
Killer Bee suggested a direct solder onto the module - not easy for an amateur like me as the contacts are very close. IT WORKED :w00t::lol::cup-1:
Next to assemble all and, well, charge batteries and fire her up!! (It's been perhaps 4-5 months since the MT's turned a wheel in anger, so all was double checked - bolts, etc., glue on the tyres (seems OK).
First few pulls .... I hear a few clicks in the pullstart and the cable doesn't rewind
The 'old' pullstart was one of those chrome CY option pullstarts, that actually had an alloy pawl, and was working perfectly.
I had threadlocked the old retaining bolt into the alloy cover, so .... nothing's easy!! A bit of sawing to permit a rather heavier duty screwdriver and it's off and the replacement installed, steel cable replaced pull-chord again.
Time to re-assemble and try again ....
Considering the motor's been on a shelf for 7-8 months awaiting installation I'd been putting the nearest 'best option' oil in to line the cylinder - nitro after-run oil - so I expected a difficult and smokey start.
The compression's obviously more than the previous G260RC, which was still running very well, and more than the G240RC 4-bolt in the Macca.
When I was about to give up, it, erm, 'burped' - GOOD SIGN.
10 seconds to rest the shoulder, then on second pull, she fired up.
I'm running a Walbro 813 and found that L/H settings were 1.1/1.2 +/-, so I've set it on the default 1.25/1.375, so I expected it to run rich - and it does, but I prefer it this way - new, tight engine. That was 19:30 yesterday, so I only ran it lightly with very slight revving for perhaps 5 minutes.
It fired up fairly easily today and I ran it for perhaps 15 minutes. A sudden burst of heavy throttle had it hesitate a bit which I've put down to being tight and over-rich - don't see it as a problem.
Bottom line 1, it's very shiny but doesn't linger on a shelf!!
Bottom line 2, as mentioned above, there's no replacement for hydros, and with a truck this heavy, it SLOWS quite well, but doesn't 'stop on a sixpence' as I would like .... that's for the future ...
Here's the photos.
What do you think? .... (Constructive) criticism accepted. ... !!
