    I like to make some comments about the Grubee. 1st off the 49cc china is a blast no engine problems. The gears scream until broke in. The gas tank cap leaks should come with a cap w/breather or cap off a good weedeater like echo. If it ever falls over make sure you check alignment. The rack is weak to sideways movement. Customer support is poor. I have a lot more to say but will leave you with this I love the setup despite the problems. I am working on some improvements. You Grubee boys need to return e-mails. Ok go ahead and slay me now.

    Which Grubee dealer did you get it from? As I understand it Grubee does not sell retail.

    Went snow riding saturday I attached a third wheel for stability. Weirdest thing to get used to but fun when you figure it out. No problems with engine or drive though I did up the idle to keep from staling. It was cold 10 to 15 degrees. I played around for about 3 hrs maybe 15 or more miles.
    Has anybody been out riding in the snow? How do the 2 strokes perform in the cold?

    My friction drive won't handle the wet, but when it was -9 (f), the Mitsu 43cc started fine.

    Wanted to give update on Grubee rack mount. She is still running strong.
    No engine problems. No tranny problems. The gear box becomes smoother and quiter after several hundred miles. My only complaint is strenth of the rack. Rode yesterday, cold as ****. Twist the throttle and peddal gets the front end up easily. If I was a better rider I could ride a wheelie for blocks.

    4 Stroke (49cc) Engine Kits Question

    As some of might know I am into vintage motor bikes and build some of my own from scratch using any and all engines available. I mainly collect and mess with
    the purpose built motor bikes from the 1930's to the 1950's fad that happened.
    I sold my 2006 Whizzer Rider and my 1950's Cyclemaster Rider recently and since spring is right around the corner I want to build up a couple more bikes for friends and family that come over to visit.

    My question is what 4 Stoke kits are the best at the moment and working?
    I'm sure if I read through all the posts I might get a idea but this is quicker.

    All input appreciated. I'm not interested in the politics just what is working!

    Thanks Roy

    Good question. I have not run the gebe kits but have used Robin subaru engines and their quality is very good. I run the Grubee kit w/49cc engine. The reliability of the
    huang shea engine has been good I have over 1,000 miles on it. Murphy's law kicked in when I posted no problems. The spring on the clutch broke, nothing big except the spare clutch inside diameter (clutch and housing) was to too small and had to be reamed out as did the key-way. I spoke with Josh at birddog and he said the were being milled at a different machine shop,(Chinese quality control). Josh did offer to replace if I couldn't make it work. The clutch housing was worn quite a bit around the bushing. Over all they are pretty good units though I would like to get more than a thousand or so miles before replacing parts. I will be taking some pics for the visually needy. Yuk, Yuk.

    Update on the Grubee. I estimate I have close to 2,500 miles on it. I developed a hole in the diaphragm and rebuilt the carb yesterday, Walbro carb kits work on the updraft carbs (K10-WY). The small gas tank that come with the rack kit has been replaced with a 1 gallon gas can. The larger tank lets me ride all week with out a fill up. This bike has been rode hard wheelies off speed bumps, curbs, I even jumped it at close to 30mph. When looking for parts I don't like to wait for online deliveries. My local sources are motorcycle shops some KTM's did use 415 chains, moped shops, bicycle stores and, lawn mower repair shops. The ease of getting parts and finding someone to repair or service your bicycle is in my opinion a major disavantage for more use of motorized bikes. Opinions?
