Scrappydogs big bore kit for the Linhai 260-300 cc engines By 4950cycle (Read 2,299 times)

After all this time no one has ever bought and/or installed this rather expensive mod ? I want to buy and install the big bore kit on my JCL MP250A Linhia scooter engine. But I have absolutely no verification how it will effect my performance. It has been quite a while since I've been looking for the elusive person that may have bought one of these. Still no one has one huh ??

No experience with this particular "kit" but I can tell you 40cc bump in cc's is not going to be a huge increase in power ,,,I think the route of free flow air filter ,,a decent exhaust and reject the carb will yield better results for less money,,,and add a more aggressive cam and it'll be evenbetter

Does that A9 sport spec cam Scrappy offers (out of stock though)fit a 260 Linhai ?

[cyborg]

Not sure about that,,,I doubt it,,,a completely different engine,,try the pipe free flow intake and carb rejet,,,I think you'll be pleasantly surprised

I do know that I had a KZ 650 with stock bore "But" It had a 3/4 cam installed (what ever a 3/4 cam was), jetted, and a Kirker header. And if I remember right some head work done. All the work was done by a professional. I bought the bike that way in a distress sale for $600 back in about 84. It was a 79. Anyway, this bike was one of the baddest arse bikes in Fort Lauderdale at the time. It took a worked up Kawi 900 to take me "not stock, no way". Everyone that liked bikes wanted my bike. Finally someone stole it. Anyway, The moral of the story here is " Breathing, breathing, breathing. Thats what makes noticeable HP. Not fairly small displacement gains. Just like Cyborg has mentioned above. So I certainly agree with you Cyborg. Now ! Where can I find a cam for this thing that will make higher RPM power.

Why not pick up the telly and talk with scrappy? I have talked to them a few times and they really know their stuff.

[4950cycle]

Great idea jct842. Think I'll do that when I can find a free moment here.

I was going to buy a 300 kit on eBay, then got to looking at specs for wridt pin. The 300 piston actually uses a SMALLER pin! BUT!/But, that was the stock piston. I had planned don just buying. a300 cylinder and piston kit but.... I nevr kbew they had a bbk for these.

[jct842]

If it was me I would stay stock. You are not going to get gobs of power and even if you did it is still a scooter with scooter handling. Reliability so much better as stock too. If you want to go fast get a bike.

[2stroked]

Yeah. I wasn't doing it for the extra power. I actually found the 300 cylinder fotghe same price as stock. Thtas what made me want to go to 300.
