  1. I can't comment on the lever but I am delighted with this unit - smooth as butter through the full action. My TLR clutch was pretty easy but now feels by comparison like a Harley.
  2. Br40rt my other post is not a 3 position lever it is a small unit that uses a small lever and a joining cable It is very clever and very effective. Google easy clutch.
  3. Had an interesting experience that I would not recommend. When taking off for a ride I had to ride through a small 5 acre paddock that my wife has taped off with electric fence tape to keep her horse in. Normally it isn't turned on - but you guessed it... I rode up as usual running the front wheel under the tape intending to lift it over my head and proceed. But as soon as my Cota's aluminium front guard touched the tape I started to receive a whack from the electric fence unit. These things crank out short high powered zaps - we are talking thousands of volts. In my panic I grabbed the tape and tried to flick it over my head so I could get away but the tape snagged up between my helmet and my neck at the back of my head.... right on my spine! A few severe jolts immediately followed by very loud four letter words and then I blacked out. Luckily as I fell over I broke free of the tape and I was only out for a few seconds and woke up with my bike on my leg luckily exhaust side up. Had something of a strange feeling in my shoulders for the rest of the day but no signof depression
  4. Hi I have been off my bikes for several months (valid excuse available). But before my break I was having problems with hand cramp particularly when riding my Cota 247 which has a pretty heavy clutch despite the long arm. So a few weeks ago I ordered a part called Easy Clutch off ebay from a guy in UK for about $30AUD delivered (love our exchange rate)I only got it fitted correctly today and wow what an improvement. Gone from 3 fingers straining to 1 finger easy. Takes a bit of fiddling as intended for modern thinner cables but worth the effort Best $30 I have spent since I bought the compression release
  5. Original manual states - gear box SAE 90 - 300cc - I have tried ATF and did not work well - currently using Castrol VMX80 with good results clutch SAE10 W 30 - 200cc - I use Castrol GTX ( not GTX2) and have had no issues in 2 years front forks SAE20 or 30 - 190cc ATF is fine
  6. Second attempt all good - gave it a really good workout and no issues so far
  7. You put the wind up me so much I didn't put enough on and had oil coming out of the top - hear head
  8. Hi I am going to try threebond in place of the paper gasket on my TLR200 clutch case - I have good reason. But the instructions are apply and assemble in 1 minute and that is about it. I have used loctite products before and with them you assemble but don't tighten until 24 hours - but the threebond tells me nothing - I have googled and got no further so: do I assemble and fully torque the bolts how long before I can fill her with oil and start Thanks in advance
  9. Funny I have a post in another forum where my fellow Oz posters are telling UK posters that their comments are invalid because they don't understand our geography and now you are telling me that we don't understand your climate - fair enough But anyway the gasket remover is brilliant for removing just about any coating .
  10. But if the bloke before you and the bloke before him all did the same thing - that has to start having an impact on the heat dissipation properties of the metal.
  11. Permatex Gasket remover is brilliant at removing paint - even powder coat but don't get any on your skin or anywhere near your eyes
  12. I have had some fun with a broken frame but happy to say all back together and looking good
  13. Sorry if it was a stupid question.
  14. Hi - I have been away for a month - family issues and only now looking at the engine - any response on using silicon as well as paper gasket would be appreociated Also I read elsewhere that valve lapping was not as critical as it used to be - any thoughts on this as finding lapping compound near home will be tough
  15. Start with "Yamaha trials" or "twinshock trails" you can have as many as you like - I monitor Honda TLR - Montesa - trial bike, Used, 1970s plus a dozen other non-trials searches and I get a list of emails everyday telling what new listing fit my search
  16. set up a search alert on ebay eg: http://www.ebay.com.au/itm/BULTACO-TRIALS-BIKE-/130698532767?pt=UK_Motorcycles&hash=item1e6e3d579f#ht_500wt_1413

    247 Evolution

    Sold for $1200 ... which is about half what mine owes me. A Bultaco of similar condition and originality would have done much better and yet the Cota in competition was very comparable. Not to mention that the 247T can still be road registered today in Australia .. and that is not easy for most dirt bikes
  18. I have a full gasket set is it a good idea to use a silicon gasket sealant in addition to the paper gasket for the crank cases etc.

    247 Evolution

    I see today a 247T serial number only 3 higher than mine listed on eBay in Oz ...sooo tempted
  20. The rebuild is on the back burner due to family issues - however I would like ideas on whether I need and what I should buy as a valve spring compressor. I am only replacing the stem seals but I did have a quick try with some large G clamps and that ain't going to work. Since I have a bit of time up my sleeve I might as well take advantage and get whatever tools I need
  21. We aren't confusing degrees with mm are we? The factory manual says 2.5mm BTDC which is 21 degrees. 4 degrees would be a long way out - I don't trust Clymer - I have a Honda one for my TLR and it has several errors and confuses models.
  22. I run standard jets and 25:1 with excellent reliability and good performance for the last 12 months. I wouldn't listen to the modern oil arguments just run the recommended 25:1 (I use semi-synthetic) and the right plug with the right gap (very important). I also recently fitted an SM replica muffler replacing a crap after market and it makes a enormous difference at the top end - highly recommended. The Amal works well when set up as it was intended but when you start fiddling you start chasing your tail with compensation for previous compensations. The Amal is reportedly very prone to wear but in my experience, make sure you are using the correct needle and jets and that the manifold facing mount is flat (they warp easy but are easily fixed). My Cota's reliability is very sensitive to timing settings I now use factory or maybe 2 degrees retarded to improve cold starting and take some of the surge out of the low end power but advance at your peril.
  23. The standard jets are 150 main 35 idle and U2 needle. You can still get complete 627 kits from Amal Standard timing should be 2.5mm (21 degrees), points 0.4mm - my Cota is very touchy about timing and points gap - too advance won't start and too retarded easy to start cold but a bugger when warm ( doesn't make sense but that is what I find) Also check your plug gap as they really do not like a wide gap standard is 0.40
