That could happen if the timing belt slipped time. Something similar happened to a Nissan 3.0 liter I worked on a couple years ago. If the timing only skips a couple teeth it may only be off in one place. The car I was working on had a worn out timing belt tensioner pulley that caused the problem.
engine sprocket =14t rear sprocket =35t
Guessing an 11T cog (sproket), maybe a custom 10T.

i wouldn't say its big but a 22sprocket is the smallest you can get from gtrider
To find the crank timing mark, you must remove the pull rope housing. It is held by 4 bolts. Once it is removed you will see a plastic plug that can be removed with a flat head screwdriver. As for the camshaft mark. it can be found after removing the cam sproket cover. You will see the mark at the top center of the hole. The cam sproket has a line on it that must be aligned with mark at top of cam sproket hole. The line can be difficult to see until you remove cam sproket bolt.
Pull the back wheel off and there will be bolts (probably 6-8) holding the sprocket on to the rear hub. Take the bolts off, change sprockets and your done.
A bicyle is a simple form of the sproket and chain system in action.
I have a '98 VW Beetle with a Engine Check Light fault 0341 or Cam Position sensor problem. I have had this problem for about 40,000 miles and at times have tried to fix it. In responding to your "how to" request let me first say that the Beetle uses the cam position sensor to fine tune the gasoline mixture and spark to real-life driving conditions. In the event the cam position sensor stops working, the computer control system simply reverts to a built-in database of mixture and spark settings. These are just fine but may result in some increased gasoline consumption. Now for the fix-it suggestions: a faulty cam position sensor is not very common by what I have read. But the cam position sensor fault can be a result of in improperly tensioned or timed, toothed cam belt. In addition, the cam position sensor fault seems to be commonly caused because of frayed or otherwise faulty wiring from the sensor to its' connection into the wiring harness. To replace the sensor, you must remove the toothed cam belt (loosen the tensioner and pull the belt off of the cam sprocket) and the cam sprocket. The sensor is located behind the sprocket - it is easily replaced. Althought this may seem daunting, the hard part is relocating the cam sprocket correctly to the cam shaft. You see, there is no key or fixed marks to get it back on correctly. I do recommend that you get a repair book to try the yourself. The VW book is somewhat difficult to use and I have never looked at the Haynes manuals.
i did this not to long ago.i need to replace my water pump and decide might as well to all my belts to.go pick a chiltons book on the corolla and it will get you through it.the only thing i have to say is get the right timing marks.there are a bunch of "marks" that can have guessing.study the picture found in book.with me as a beginer on work on cars it took me about 6-8 hours to do the pump and all belts. how to set timing- A dot camshaft sproket line up with a cut mark on camshaft bearing cap at about 11 O'clock (you have to take out the camshaft sproket or look through the hole closely to see the cut mark on camshaft bearing cap) and on the on crank pully also have a cut mark line up with the "0" on the timing belt cover. (at about 1 O'clock).....
This Formulae works for ISO/Metric Standards PCD = Pitch / Sin(180/No of teeth) Pitch in mm Sin degrees. PCD = 57.32 Hope this works for you Hv a gud time Lokesh
Count the number of teeth you have on the motor side sproket, divide that by the number of teeth you have on the rear sproket. IE 11 on motor side divided by 53 on rear sproket = 4.81 : 1 (use the first 2#s after "." )
This depends on what chain and sprocket we are talking about. The chain and sprockets on a motor cycle tend to be available through motorcycle part retail stores very easily. The chains and sprockets from inside an engine may dealer only or available retail
