Mr D Holmes What clutch issue are you referring to on the Beta 4T. I currently have two 2018 Beta Factory 4T in my garage and recently owned a 2016 Factory Beta 4T. There are no issue that I know of. The clutch works great with the correct adjustments and oil. The Beta PDF you attached is several years old (2012) and refers to a 2T clutch set up. Please help us understand the issue.

Diesel 2607 How about Randolph's Leap or Sueno Stone .... I have family in Forres & Elgin..... Even the mechanics ground..... Surely there are lots of places around there.

Andy How about making in mandatory that people state what country they are in. It really would help out with requested advice.

As a side note. Apart from the fast or slow throttle tubes one can also mess with the cam that controls the butterfly valve. Not for the mechanical challenged though. Just change the throttle tubes i.e. fast or slow.

WOW This is a standard Beta 4T throttle tube and housing. The Domino throttle tubes are interchangeable from slow and fast. The metal housing is the stock throttle housing. The throttle cable is not connected to the slide on this Mikuni carb as it is a CV carb. The throttle cable is connected to a cam which in turn is connected to a butterfly valve inside the carb.

Mark. Another option is to install another Beta fuel solinoid from the auxiliary tank into the main system,

Not so. We ride in Arizona, lots of Cactus around and thorns. I depends on the type of terrain you ride in. We need thicker front inner tubes in AZ.

Where are you located in the USA?

Hola Miguel Where about in Mexico? I am in Arizona.

A smoking bike will be the least of problems if you don't get the lad to wear a helmet and some trials boots. His right leg is exposed to a VERY hot header pipe also.

All the jets are stock Mikuni jets with the exception of the needle (5DP) it is a needle machined by Beta for the bike.

Not surprised this happened. One of the concerns of having a shock and spring exposed is the spring taking a hit to a rock causing a point loading scenario. That can cause a small fracture and it will propagate and fracture the spring resulting a complete break of the spring. If the spring was given to a metalurgist he could quite quickly determine the cause of the failure.

Hi Mark. BillyT here. I live in Scottsdale AZ. I may have some Beta 4T 300cc information that will interest you. You can e-mail me at williamtraynor@hotmail.com or call me at 602 570 6877. Billy

Hey Gas Blocker........

If they go FI the tank will have different fuel cap.

You are witnessing not Euro 4 testing but also the very early signs of FI testing on Beta 2T's. Things that make you go mmmmm ...............

I know a guy in Prescott that works on bikes for free. Good mechanic, weird guy, funny accent.

I am sure they will get the plastic horses out his bottom bit by bit.

2017 Beta 2T 250 Factory. Terrain: lots of big rocks, slippery creek beds High elevation around 5 to 6 K feet above sea level. Average temp around 98 to 101 F Level of rider: Really old fart novice Lots of experimenting settled on 11 in front 41 in rear. Experimenting over with.

One BIG add to the above. Lay the bike on its side to change the oil filter. So much easier to get the filter back in.

You will be drinking from a fire hose soon......

I think the main reason people measure it in the hand is due to the fact that it is a pain in the ass to remove the whole clutch assembly to measure it under compression so they just do it by hand. I was fortunate enough to have two clutch hub assemblies to play with one on the bike and one on the bench.

stpauls As Oni Nou says this is a Gas Gas diaphragm clutch with only one spring in it. Now we know why you where banging your head against the wall, cereal boxes are getting harder to open these days.

Need some aspirin Paul. I do, I have to fix a friends 2003 TXT Pro 280 with a 2002 TXT 200cc clutch hub and clutch pack in it that some body swapped out a year ago. Needs a VERY strong hand to pull the clutch in. Need to put the original clutch hub assembly and clutch pack back in it. Took the clutch pack apart and all the fibre was lifted of the fibre plates in one piece. It had two 2mm metal plates in it and three fibre plates with six separate fibre rings. You can see the images down below of one fibre plate with both sides of the fibers completely lifted off the plate. On the other picture you can see the glue remnants. Has any Gas Gas owners experienced this seperation of clutch fibres before? What a mess.

The sectional drawing is from a technical bulletin from Gas Gas themselves. I have that 2010 TXT manual already. Not disputing what you are saying. I looked at the drawing again this time with a magnifier glass (old eyes). It is a compressed measurement and it is not from outside of tab to tab but rather from friction surface to friction surface. Makes sense now. The bike is a 2003 TXT Pro 280 I re -measured from inside the hub base to the inside of the large metal ring. So, 9.75 clutch pack in hand and 9.5 in compressed state. Still some compression going on there and still not 9.75mm compressed as it calls for. Seems it needs to be 10mm uncompressed to get 9.75 compressed. Are people bending those fingers to get the 17mm? Is that measurement from the bottom or top of the finger? How does the the finger height affect clutch pull in the way hardness or softness? I can see it affecting clutch lever travel but stiffness??? What I missing here?
