trike again

well I think its going to happen, I have a swingarm from a honda 250R three wheeler, chain drive and a durablue axle, this will work fine but it comes to the chain and how to adjust it. So now my mind has been clicking away and this is what I have come up with. if I put another sprocket( engine sprocket)midway down the swingarm and use it as an idler with an adjustment up and down to keep the chain tight, like on a car engine with the serpentine belt, it might work fine.The other idea is an adjustable swingarm.

I dont see why an idler sprocket wouldnt work, you could base it on the roller style cam chain tensioners

If you're going to use a "sprocket" midway down the swingarm as an idler of sorts, I'd suggest using one like ref# 12 in the pic 77KZ650 posted.
It's a rubber wheel as opposed to a steel sprocket.

No steel teeth = no accelerated wear to the chain, and it should still function well enough if the chain tension is kept sufficiently adjusted and/or the "idler" itself is self-adjustable.

I didn't follow the first thread so forgive me if I'm asking something that has already been addressed. How/ what way are you going to adjust/set the trail and how much trail are you thinking about? Have you checked out the Trike forum section at Chopper Web? tinyurl.com/ue4h7 There are some knowledgeable folks there.;)

I plan on building a swingarm that bolts on just like the stock one so it could be changed back to a bike in a short time, it will use the stock type shocks and be 23in long, stock is 19in, the tires will be 26in diameter,probably a 205x14 on alum mags, a stock type disc and more than likley a front caliper will be modded to fit and mated to a stock rear brake master so the brakes will work as normal, so far the frame is an 84 KZ700, the engine is an 81 650CSR.....damn I just can't leave things alone, give me a pile of parts I'll do some thing with them, cars trucks cycles I'll take them all apart and put them back my way, I had the hardest time when I restored my H1E500 puting back like factory made it(well almost couldn't resist the chambers)...YES I have been to chopper web
