Rob's G1 Adventure

[Snakeoil]

Thanks. I've been rebuilding carbs since I could hold a wrench. But they all have their subtleties. This Mik has an air jet on the outside. Never ran into that before.

Glad you brought up the manual. My G1 is a G1A1 1981 model. Yet it would appear that the manual in your link and posted in a sticky is for later model machines. I assume most of the engine info applies.

Was/is there another manual for earlier G1 models? I would think that there would. Afterall, they would not wait several years before they publishes a manual.

Thanks again for that tip. They have been very responsive and helpful there.

I did a compression test and got 120psi. So, looks like rings are fine. Need to order crank seals and maybe a new carb. Do you guys buy the carbs from ebay or go with OEM Mikuni carbs? I'm sure the Mik is probably 4 times or more the price of the carbs on ebay.

you maybe able to find OE seals but i doubt youll find an OE carb.
ive used the ebay seals and so far so good. the carbs are hit and miss and ive seen folks combine parts from both to get a working unit. the carbs are like 1 in 3 are decent but we dont have much choice. doesnt matter if the carb is listed at $18 or $58 they are all the same "mokuni" chinese rip off of the oringal mikuni carbs

Crank seals are ordered. As an interesting sidenote. I looked at all the seals offered on fleabay. There are at least 15 different vendors selling the 2 seals as a set at the same price with free shipping. I started to look at the location from where the seals are being shipped, and every one of those vendors, all with different ebay names, is shipping from Hebron, KY. Others vendors seem to be selling the same seals for different prices and from their particular locations. All the seals look to be the same items. When I get mine, I'm going to measure them and see if I can source them from my local seal and bearing supply house.
