Over here we can buy a product called Viagra Moose for impotant tyres. This Viagra Moose will keep the tyre up for the trial no problem in fcat you may be able to play longer than the bike is willing to. I believe JTT has a link to the web site that sells this stuff? You can e-mail him and ask. BillyT

Does anyone know who is the best contact for getting info for trials in and around Glasgow? Surely there are some riders within the area? Any feedback would be appreciated. BillyT

Dr Nick One can not simply say what is right for you they can only offer a starting point from which you can experiment from. Think of the fork oil weights as another tuning tool. The oil weight that you do end up with should allow/afford you the ability to have the suspension dial/controls set in the middle of their adjustment, this way you can fine tune them for terrain and slight weather conditions on the day. To really appreciate what I am saying, drain the oil out of the return side/rebound. and go for a short test ride. The bike should still be somewhat controlled on the compression stroke but should fly up out of control on the rebound stroke. This allows you to feel what ligher oils can do, you the can fine tune to taste. You will not feel a big difference from the same weight of oils in the forks as you would going to extremes, meaning you would really notice a change in say 20 on the comp side and 2.5 than you would 2.5 on both sides as oppessed to 5 on both sides. I have had riders in the past use as much as 15 weight in the compression side and 2.5 on the rebound. And one rider with 20 weight in each leg. A lot depends upon your riding style (how agressive you are, like how big are the rocks or ledges you are dropping off) your body weight and the climatic conditions you live in. Just like in your cars engine oil a colder climate will see the heaver oils get really stiff and lethargic on you, were as a light weight oil will get very thin in very hot Arizone/Texas summer weather. I had riders change the fork oil weight seasonaly I would recommend you always use a lighter oil in the rebound side, but only you can be the final judge in how it suits you and your riding skills. For example guys that like to hop like bunnies in the section use very light rebound oils with high spring rates. One of the reason Beta recommends the same weight oil is that it is easier to ship the bike out that way as it means they do not have to keep two inventories of oils and maybe even get them mixed up in production, but also they do not know were the particular bike will end up in the world ie climate/weather how much the rider will way etc riding skills. I would start with 2.5 in the rebound and 5 weight in the compression side. BillyT

Dr Nick and to all Keep in mind that most trials forks are usualy broken in to the following: One fork for compression One for rebound. What tends to happen is that a rider thinks his supension is to soft or bottoming out on the compression so adds heaver oil to both forks. What he does not take into consideration is that the rebound will also be slowed down by this heaver oil. One can use two different weights oils for each fork. I personaly use a 2 1/2 weight on the rebound side and a 5 weight on the compression side. This way it does not bottom out and also returns briskly without a pogo effect either. BillyT

Thanks JTT that was my post. I have worked on many different carbs throught the years and they all have one thing in common: physics.............I can use my basic physics knowledge and years of black magic carb tweeking. These basics apply to any and all carbs. The big problem out there is that everyone and their brother adjusts their carb differently, they can imagin that a carb is running rich when in truth it is running lean and vs versa. Misconceptions about what particular jet does, and when run ramapant. There needs to be a standard way of checking your carb for basic set up, fine tunning, and re-jetting. If we all use the same standard the helping each other out would be a hell of allot easier. Carb tunning is like elbows we all have one and we all have an opinon on how to set it up. A carb is also a very personal device what works for one bike may not work exactly right for another indentical bike. The same holds true for the rider he may like his carb set up one way and another ride wants a whole different set up. The bottom line is that the carb basics must be estabslished no matter the rider or bike or even the type of carb installed. Lets try and establish this standard and then move on and help each other. Any takers for establishing the carb basic, one voice one standard. The ball is in your court guys, I can help with setting a standard and posting some digital pictures and charts/graphs to help us along. BillyT

Before setting out for the day. Get a hairdyer plug it in and blow the hot air on the carb bowl/body. The bike should fire right up and run good all day long. This works brillantly.

It was the night before xmas and all through the house nothing was stirring not even a fourstroke. Awe the best fellow riders. BillyT :santawink:

Hello boys and girls. Thanks for all of the e-mails letting me know were to find you. I thought I was in a strange place when I logged on. I was and it was nice. Good work Andy. I have been busy working on "Viggen" A Viggen what the hell is a Viggen. A four stroke fuel injected trlals bike. Think of this 250 Four stroke Mikuni partial fuel injection Showa front and back suspension. User programable ignition (on the fly) Rear fender attached to the swing arm (for greater clearance) Foot pegs that rotate slightly for better balance. No sub frame Replacable carbon fiber boot guard areas. Disc brakes that are inside the spokes attached to the hub. A single sided swing arm Gas inside the frame. Run flat tires A heads up (HUD display inside the helmet) tach to tell the rider when to shift gears for better usage of torque range. A weight of 120 Ibls Four gears with the fourth one changable by the owner An electronic reverse gear switchable on the fly in a section. A memory chip for remembering what your score was in each section and what gear and rpm range that you rode it in. And lots more goodies that are in the works. :madsanta: All the best Mad BillyT
