Starting a 1989-2008
THis is the advice for a 2004-2008 650 Husaberg I gave just now.....
"I urge customers to buy 2-3 things when they get the 650.
The starter repair kit (SRK) as you have seen is excellent. https://www.taffmeisters.co.uk/product_info.php?products_id=948
An iridium plug such as the IXU24 Denso plug which I no longer stock but I have the NGK DCPR8EIX - the NGK equivalent https://www.taffmeisters.co.uk/product_info.php?products_id=711.
The pilot screw must only be set when the engine is warm for the highest idle it will give. The PS is underneath the carb. After this, the idle must be lowered only on the idle k**b. Repeat this process a second time.
Very often you find the PS likes two positions. For example; 1.25 and 1.5 turns out. Try and restart the bike with the PS in both positions and one of them will be better for restarting than the other. Remember, if you're just ¼-turn out and they don’t start!
The improved auto decomp spring. https://www.taffmeisters.co.uk/product_info.php?products_id=922 The engine MUST decompress! What we have discovered with the 650 over the years is that as soon as the sprague starts to slip, it will always slip. Look at the ‘nipples’ and if you can see a ‘flat area’ then it is finished. Kaputt! The 650 can wreck a sprague bearing in 15-minutes and 20 attempts as it starts slipping. Too late.
So, the 650 must always start with a new sprague bearing https://www.taffmeisters.co.uk/product_info.php?products_id=375 and from the off you must fit the SRK. It comes with instructions…. In English of course!
I have always encouraged SEMI-synthetic oil for better starting. Fully synthetic ruins the starter gears - and the clutch steels.
You will of course have a CTZ7S Gel-cel battery or have gone to an even more powerful Li-on battery.
Finally; valve clearances. 1/6th of a turn and Taffy’s GOLDEN rule; You must be able to ‘morse-code’ the tappets and hear the tick-tick of the tappets at the rear licence plate… only just. 1/6th of a turn yes BUT, undo a little and then a little more for the ‘morse code noise’.
Hope this helps. Unfortunately with Facebook, all messages soon get lost.
