when starting, especially cold, electronically it drags on the first stroke. even with a new battery it still struggles. ive been told it could be due to high compression. If compression may be to blame, what should it be?

when cranking manually, it seems effortless.

Any ideas?

did a quick search and didnt see ne threads so i hope im not :beatdeadhorse5c:

      2005 Suzuki King Quad Battery Question
      By LMI
      Hi all.  New to the forum & quads.  Seems like a great place full of info.
      I just recently picked up a 2005 Suzuki KingQuad LTA700.  I need a battery.  I've been reading up on conventional vs AGM types.  I have a Royal Distributing and Canadian Tire.  RD has 2 types avail for my year/Model a battery YTX16-BS CRANK $75, and BATTERY YTX20CH-BS YUASA $140.  Neither of these is the type from the manual FTZ16-BS.
      from what I can tell... I think the only difference is the capacity with the $75 unit rated at 14 AH/10HR and the $140 unit rated at 18 AH/10HR ... which is the rating in the manual for the FTZ16-BS.  How much does this make a difference for nearly x2 the cost?
      And about the models/type numbers.... what is important to know ... they all end in "-BS" but are the other details relevant or just manufacturer naming?

      Timberwolf 250 starting issue
      By Jdeaton011989
      Hi all. I have a timberwolf 250 2nd that will not start.. I thought it was out of time bc the guy I got it from said it just quit on him. The tensioner had a nut welded to it and it was like2 teeth off. I installed new tensioner and chain and it still will not start. It has fire and it will not hit off brake cleaner. It has compression. Haven't put a gauge but I'm sure it will crank and run with what it has. I double checked my work and it's still in time. Spot on. Both valves move. I'm about to put a feeler gauge on them and I'll cone back but other than that any ideas?

      Starter not staying engaged while cranking
      By HoldenBoy
      Hi all,
      Looking for some help on a starter/bendix issue. Can Am outlander 450 2017. While cranking to start, the starter spins and engages into the ring gear. After a few seconds the bendix retracts while still spinning and there is no damaged teeth on the drive pulley.

      2001 Big Bear 400 4WD - Battery Removal any tips
      By tds7
      The battery on my Big Bear drops completely down in the battery compartment nothing sticks up to grip too, plus there is only 1/8" clearance along the sides, no way to get a grip on it to pull up out of battery compartment. I thought about putting a piece nylon strap under the battery and leaving enough up each side to give me something to pull it up out ff the battery compartment or using a big zip tie around the battery.
      Any others have any ideas or have had this issue.
