[jakep53]

Nice work t's gonna look great when its done!
as a teen (a little younger than you) I understand how hard it is especially cause i'm in OZ and everything is basically double the price

[Samjp22]

Hatc gonna bring that thing to TF?

Haha, I'd love to man but I am going to the St Anthony Sand dunes that week and weekend. Thats what this trike is being built for!! The Sand! Otherwise I would if it wasn't the same weekend.

Man this is going to be GOOD!!! One suggestion...

I always felt the '87 would look better with a RED SEAT...but either way your trike is going to ROCK

[TrikeGarage]

Well done man kick ass build your off to a great start I'm sure the 330 will be a handful lolol.

[pantera1975]

Your decals you have ordered will surely set it apart.

You're doing an awesome job, keep up the good work! I wish I had that kind of motivation when I was your age! Very impressive.

Haven't updated this in a while. Here's my recent progress. I know I am running the 87 scheme, but I am not running any blue, just beware of that.

Maybe I missed it in the thread, but what version of the 330 are you using? . The bolt on or the machined case one? . ATC bottom end or the TRX bottom? . Depending on witch way you went, I may be able to steer you around some of the "small" problems with the ESR 330.

I am running the Non bolt on. The 4mm stroker crankshaft. Machined case, and its an 86 ATC bottom end.

Non bolt on is good. ATC bottom is good also. I'm running a TRX long rod bottom and it creates fitment issues, so your good there. You didn't say it was a power valve, so I assume its not. Unless ESR has changed their casting, they use the same cylinder for the power valve and non power valve applications. They just don't machine out the material around the exhaust port around the non power valve style, leaving poor cooling in that area because there is no coolant getting there. They run fine in the quads where there is a lot of room for air to get around the engine, but in the ATC it is a very tight fit and they run VERY hot!. I strongly recommend you run a temp guage. Not the ESR type ,they are useless. Get the digital one from Trail tec that you can clamp to the bars they are only 10 bucks more. Your rads have to be in top shape and you might have to run strait water or engine ice just to keep your temp down below 220 deg. Race gas, fat jetting, aftermarket over size rads also help , but just a little.

^^^good advice!!^^^

Saw your pics on FB last night Jonathan... You're doing a TERRIFIC job!!! Nicer than mine!


Just want to warn you so you can address it before you get too far along adding components for assembly: Being that you are running a stroker and no doubt a cylinder spacer, you are liable to have some tight clearance for your sparkplug and more importantly getting the coil wire connected to it. Make sure you check that out and address it before you get tank and rads mounted. It will just be easier to deal with now rather than later. You might have to run a shorty plug. Myself, I was able to get away with just a compact spark plug boot like you might find on a chainsaw or weedeater. I'm running a stock stroke 350 so no spacer for me. Thats about the only thing that gives me hesitation about a stroker....
