I'm thinking I can keep my current setup pretty much intact if what ocscully said on my thread on the other forum is true, and that is that the pocket bike clutch will in fact mount up to the Titan.

The Honda with the clutch on a jack shaft is still tempting, but the price is much higher..I still have a little thinking to do.

Conrad,

let me try to clear something up here The part that I said would bolt up to the Titan is the Housing and its clutch bell. Not the clutch itself. The pocket bike clutch you linked to at the other forum is for a tapered shaft. I don't know if it will fit a Titan or not. But the Housing and clutch bell fill fit assuming that the clutch bell is 76/78mm dia. The Titan motor as sold by Dax includes is own clutch (shoe pack) but no clutch bell.

Oops, sorry. I meant to type housing not clutch..

Edit: Double oops, I thought earlier when you had said that the clutch and bell was apart of the cost for the grubee gear box that you meant that you had to buy them separately..but I've just come to realize that it's all one unit if you buy the gear box for $120.

So many decisions and things to weigh out..I just want my bike!!!

Edit 2: Ok, so I just got a pretty exacting measurement on one of the pocket bike clutches and the OD of the clutch is 83mm. Oscully, I believe you told me that the Titan needed a 76/78mm housing. Does this mean the Titan is out of the running for the pocket bike clutch bell?

Edit 3: This is starting to become ridiculous to me..I just got the measurement off of yet another pocket bike clutch that has an OD of 74mm which I'm thinking would mean that the housing would work..oh woe is me...

Edit 4: Ok, just shoot me in the face: 78mm outer clutch bell housing. And this is the one that I originally linked to..my brain if fried...i mean is fried. See! Gosh!

LOL Conrad! Does get draining, eh? Each option creates parameters that cause concerns that create "have to's" An enigma wrapped in questions surrounded by what if's.

I can't spell it close enough but there is a Japanese phrase pronounced "Shin dow goo" The literal translation means "Demented Machine" but denotes a device designed to make one's life easier but seems dedicated to the opposite.

For this build, I am planing to go clone, Grubee reduction gear, home made (flat stock with 4 U bolts) mount although you got me thinking Ocscully! and a thumb throttle on a Felt bike. Keep it simple and as home built as possible. So is a 4 stroke bike for around $700

Bike has steel frame and I really want to do a fancy inframe gas tank.

, ayup, keeping it simple.

Side note; Ya know when some one comes up and asks "Did you make that?" I really want to say "yes" and not "it's a kit. You just bolt it on"

Yes sir it does, but here it is nearly 5am and I'm still up just thinking away. I think I'm probably going to end up going with the Titan and a pocket bike clutch..so far from what I've found, and what oscully tells me, it should work. But now I'm afraid I've made a gross miscalculation in my gear ratios in that I originally did not factor in the change from #25 chain on the input side of the jackshaft to #40 chain on the output side. Right now my calculator is just crunching the numbers using tooth count but a 10 tooth #25 sprocket is half the size of a 10 tooth #40 sprocket.

So now I'm off to make a thread about ratio help, but I think I'll hit the sack first and start fresh tomorrow.

Until next time...

Would chain size make any difference? Dang it. LOL

I know, I wish the pocket bike clutch could come with a #40 sprocket but they only come with #25 so I have to have two different types of chain..it really stinks

Can you just swap sprockets? LOL, ain't no one getting any sleep tonight.

I don't think so, the sprocket is actually one piece that screws into the bell. Here's one for reference. As far as I know they only come in #25.

Well, I just found this and it has me worried again..

If the mounting holes on the Titan are 75mm center to center then this presents me with a problem..

If the bell housing would still fit then I could probably drill the holes out and use some washers to hold it together.

Any ideas?

Edit: Ok, I don't know why I thought someone had told me that the mounting holes on the Titan were 75mm center to center but I just found this which says they're only 70..which is close enough for me
