Re: Inviting all those who have a knowledge of Motorcycle front forks!
First of all that's great you have started the project on your own without any automotive background or help in that section, that takes a lot of courage.Originally posted by Loner_wolf View PostCAN ANYONE ANSWER THE FOLLOWING QUESTIONS ON THE MOTORCYCLE FRONT FORKs
1. How does the fork length matter? I mean, I have seen bikes with taller fork size been reduced by affixing the triple trees a lot below the original position making the forks stick out.
2. What are those nuts/bolts called that hold the forks to the triple trees? And where do I find these beautiful bolts we see on the internet here in India?
3. How do I get the triple trees to match my forks? Do I need to purchase them as an assembly or those have to be custom made? if they are custom made, who makes these here in India?
4. If I have no knowledge about motorcycle forks, but can but and bolt, can I replace a motorcycle myself or is there any critical technical procedure involved?
5. What would be your advice for someone like me who has almost no technical idea on motorcycle forks and who have started building his own cafe racer at home (not a workshop) and who has no one else to guide him?
Thank you.
Answering your questions-
1) The forks manufacturers make are specified for their machine, it's weight, ground clearance, damping rate, handling characteristics nd other parameters. So you should install one which matches your configuration. The ones you've seen sticking out from trees is just the simplest way to reduce font height. It's generally done in case of cafe racers.
2) As much as i have seen that are the tempered allen key bolts and they work well for me. I have used them on triple trees of Duke, caliber and karizma. Remember all the nut- bolts should have mm thread. Normal nut-bolts have different threads, u should buy everything from a automotive parts shop not a hardware store.
3) The triple trees and the forks should be of same motorcycle that you want to install. Only thing you need to modify is the neck stem of the lower tree clamp (the part which goes into chassis neck). You have to put the stem of stock motorcycle in the tree of your new forks. That may need a hydraulic press.
4) There is not much to do with installation of new forks, you just need to insert the bearings and neck cones of suitable size according to your neck and tree clamp. Grease them properly. Make sure the handle is light to maneuver.
5) There is a lot to learn from YouTube and discussions like these. YouTube is a great tool for how to do like stuff as it guide visually to follow the procedure. However some items are not present there yet, but most of it is available. I could suggest you some channels if you want.
Thanks!

I have been able to figure out how to adopt the Stem and clamps of the FZ in the CD 100 neck stem. What I did was, I headed to a machine shop and got the neck stem shaft of the FZ (which is bigger) replaced with the stock shaft. While doing that the only issue I have come up with is that after install the top clamp from the FZ (which is pretty thick than the stock clamp of CD 100) the shaft seemed to be ½ inch shorter. So, I had to ditch the Star bolt and now I am holding all those together only with the top steering stem bolt. Problems with the forks is almost solved.
However, now i have come up with a new issue. I want to get the 19" RE Bullet rear wheels. But the chain sprocket assembly on the bullet is to the right. I am thinking of keeping my stock wheel hub and jus replacing the spokes and rim with the RE's. Will it work??
Thank you.

Re: Inviting all those who have a knowledge of Motorcycle front forks!
If you want to install the spoke wheels you should use from any other bike like the old pulsars and the new bullet classic, its 18 but still look good and wide enough for cafe racer look.Originally posted by Loner_wolf View PostThanks a lot Hitesh.

If weight is your concern you could use one of calliber or Yamaha rx100 rims. And there are a lot of other models with spoke wheels, from the bullet it would be problematic.

Bullet Classic? You mean the RE classic? I have a RE Classic Desert Storm 500, but that too has the breaks and sprocket on the right.Originally posted by Hitesh Harry View PostIf you want to install the spoke wheels you should use from any other bike like the old pulsars and the new bullet classic, its 18 but still look good and wide enough for cafe racer look.

Re: Inviting all those who have a knowledge of Motorcycle front forks!
Maybe i got that wrong. I mistakenly thought it as tge setup with disk brake as in the thunderbird. But you can go for another motorcycle rims like tvs Star city, hero splendor, passion, any old motorcycle i mean they are readily available in the second hand market and would be compatible with brakes and sprocket.Originally posted by Loner_wolf View PostBullet Classic?

Re: Inviting all those who have a knowledge of Motorcycle front forks!
Yeah actually i was thinking about it but I am a little confused. If I drop the idea of the 19" and decide to go for 18" both for the front and rear, can i use 100/90 on both the wheels?Originally posted by Hitesh Harry View PostMaybe i got that wrong.

Re: Inviting all those who have a knowledge of Motorcycle front forks!
Yeah you can use 100/90 r18 for rear but for the front 100/90 r18 is hard to find (as in my state, don't know about yours). Using 18 or 17 would help you reducing some weight also. But don't use the rear tyre on the front as the grooves/treads have different patterns and also the front tyres are lighter as there are less number of Plies (layers).Originally posted by Loner_wolf View PostYeah actually i was thinking about it but I am a little confused.

Re: Inviting all those who have a knowledge of Motorcycle front forks!
Okay thanks for the info there. I don't think so I'll be getting a 100/90 on the front.. let's assume that i don't get it, what are the disadvantages if I use the rear tyre on the front? Also, it is to mention that this isn't going to be a performance motorcycle. It'll be purely built for the looks and appeal whatsoever. That means it won't be hitting 65+ kmpg under any circumstances!Originally posted by Hitesh Harry View PostYeah you can use 100/90 r18 for rear but for the front 100/90 r18 is hard to find (as in my state, don't know about yours).

Re: Inviting all those who have a knowledge of Motorcycle front forks!
The front tyre is not just about the speed, it affects a lot more than that, like if you put a rear tyre on the front then the handling would become tough and the grip would also suffer especially in wet road conditions. There's a fair reason why manufacturers built front and rear tyres separately, else we should see only single type of tyre in market and their work would also be half.Originally posted by Loner_wolf View PostOkay thanks for the info there.

Re: Inviting all those who have a knowledge of Motorcycle front forks!
I get it now. Hey, Harry I just came across a Pirelli 100/90 - 18 front tyre Tubeless (customers are claiming to have used it with tubes too). Can you just have a look and check if it meets my requirements??Originally posted by Hitesh Harry View PostThe front tyre is not just about the speed, it affects a lot more than that, like if you put a rear tyre on the front then the handling would become tough and the grip would also suffer especially in wet road conditions.
