I'm just starting a project to build a custom bike based on a 1996 Sprint 900. Never done anything like this before, in fact only ever done basic servicing. Any suggestion/advice most welcome. I've been inspired by the projects by nkildiff and cavsp3. I'm planning a retro styled brat or cafe racer. Not sure what I have in my head falls into a specific category. Probably, as a newbie I should have used a kit such the CRK, but "in for a penny..."

My first specific question is what forks would slot into a Sprint without to much work. I've read that 900 Speed Triple forks would work?

This is a recent pic of the strip down. It doesn't really show in the pic, but the paint is in truly awful condition.

You'll find that most parts from the other T300 variants are interchangeable, due to the modular factory build. Forks from a Speed Triple are the same as the 900 Daytona and later Sprint Sport. The only differences, as far as i'm aware are that earlier versions are slightly shorter and sit flush with the top yoke and later ones are longer and sit 28mm proud of the top yoke. there will also be variations in fork oil capacity and air gaps but a decent workshop manual will tell you all you need to know. :)

Why not just buy a version of the T-3 that is more to your liking ? Underneath the plastic, they are pretty much the same. ...J.D.
wheres the fun in that? Some of us want something just that little bit different and the early Hinckley bikes are a perfect starting point because as you allude to......they are pretty much interchangeable underneath their outer clothes :smile2:

Patrick....I went down the CRK route as I had never done anything so drastic before either, just maintained my own bikes but always wanted to build something a bit different. Do check out the CRK site as Ian has produced and sells plenty of parts that can be used on a standard T300 as well.

Incidentally, I am using Daytona forks on my Trident, a straight swap and fully adjustable. Good to see that you have the 4 piston calipers on your bike, they make a huge difference. One thing to be wary of is changes to the intake system. Lots of folk change the intake side and then spend ages trying to get the bike to run something like it did as standard. It's like folk say....Triumph do know a wee bit more than your average Joe in the home garage but why oh why did it have to look so ugly!!!

Good luck with your build and keep us all informed.

Yes, that's exactly my motivation. Also I'm keen to learn, and what better way than to completely disassemble a bike and put it back together changing things to suit my personal taste.

Bike is now pretty much fully disassembled. I'm working my way though cleaning/polishing everything.

I did very seriously consider going down the CRK route. I spent a long time looking at their website and viewing their videos. In the end I decided to go down my own route, a decision I may live to regret :grin2:

I've just bought some of those forks. From a Speed Triple, but identical to the Daytona forks. The forks and stanchion on the donor Sprint are very tatty and would need a lot of work to bring them back from the grave. So actually it was no more expensive to get the fully adjustable forks in good condition.

The airbox thing is a worry in the back of my mind. I really, really want to get rid of most of that ugly gubbins. I understand I'm very unlikely to beat the Triumph engineers at their own game. I've read your posts on this and hope I can get the bike running well with the right jetting.

I'm also planning stick coils and have posted about this in your thread https://www.triumphrat.net/2003959772-post32.html

It seems to be a problem with the Mikuni carbs, especially with pods, Keihin don't seem to give anywhere near as many issues. Anyway, you'll sort it.

I was dead lucky with my forks....I decided that I had to swap my std Trident forks which were way too soft and it was just then that Triumph had a clear out of some old stock, brand new Daytona forks for £300, I couldn't believe my luck. Also picked up a brand new set of 4 piston Nissin calipers for £200 to replace the std Trident 2 piston units which were scary.

I should have a spare stick coil and R6 connector knocking about, I will try to find them today and see whether the connector looks the same as the ones you are buying. The coils came off a Triumph 650 or 600 Daytona but TT600 and Thunderbird 1600 also fit I believe.

As you say, you'll learn a lot about your bike and will end up knowing every inch of it and having something just that bit different. Any ideas for the paint yet?

That's interesting about the different carbs. I wonder if it's possible to swop to Keihin carbs (if I can find any). I'll do a search through the forum.

You got a real bargain with those forks. I paid almost that for used ones.
